Differences in the effective dose were due to the slower and reduced percentage of dermal absorption compared to oral absorption. It is highly water soluble and thus has potential for leaching into groundwater. The second row shows the dependency on the total respiratory rate Jtot, the radius of the cell R and the thickness of the membrane d. concentration difference between the cell centre and the inner side of the membrane Δc(R). Propoxur, or Baygon, is an important carbamate insecticide used primarily against household insects and pests of domestic animals. Resolution of all compounds except BPMC and propachlor was obtained on a 10 m×50 μm 5% phenyl methylpolysiloxane stationary phase. A metabolite of propoxur, 2-isopropoxyphenol, was measured in urine samples collected from the study's participants. Propoxur [2(1-methylethoxy)phenol methyl carbamate] is a carbamate insecticide used alone or in combination with other insecticides in interior crack-and-crevice treatments, room foggers, flea and tick sprays, flea and tick collars, ant and cockroach traps, insecticide tapes, ant and cockroach sprays, wasp, bee, and hornet sprays, and flea and tick dips for pets. They conclude that respiratory protection where oxygen-sensitive cytosolic enzymes are protected by rapid respiration does not play a role for FNR-dependent gene expression. Coefficient for erythrocyte plasma membrane. Storage: Propoxur at the rate of 0.94 g of active substance per 10 g of tape. The detector flow cell volume was 710 nL made from a fused silica capillary (0.32 mm i.d.) Carbofuran, its 3-keto, and 3-hydroxy metabolites extracted from the gullet of a bird were analysed by multidimensional SFC/SFC. The LOEL for maternal toxicity (cholinergic signs) in a rat developmental study was 9 mg/kg-day, with a 1-day NOEL of 3 mg/kg-day. It is still an open question whether these calculated values support the hypothesis that near- and intracellular oxygen gradients play a pivotal role in the oxygen response at and below 100% AU. Dietary studies have indicated that in addition to high doses, the urothelial effects of propoxur are dependent on high urinary pH. These same authors conducted additional work comparing the same reagent gases for the chemical ionization of a larger group of carbamate and acid pesticides. The 95th percentiles of the absorbed cycle dosage for the respective work tasks were as follows: aerosol (1%) applicator, 2.30 μg/kg-cycle; bait (2%) applicator, 0.61 μg/kg-cycle; spray (0.95%) applicator, 0.32 μg/kg-cycle; and spray (70WP) applicator, 8.0 μg/kg-cycle. The studies and data, which formed the basis for estimating worker exposure, were based on passive dosimetry using patches attached to clothing. The monitored activities in one location took 1.8 h to complete. Basis for Listing: AB-US EPA. A flow-switching interface demonstrated the use of two 50-μm-i.d. Acute intoxication by propoxur is resolved within a few hours. Figure 2.6. Consequently, the dose-response data of adverse effects observed in short-term dermal toxicity studies were the initial choice as the basis for calculating margins of safety for workers with short-term exposure to propoxur (Cochran et al., 1997). In particular, the diffusion constants in cytoplasm and membrane are critical parameters whose values are experimentally assessed in artificial situations. Although nitrous oxide, especially when mixed with alcohol modifiers, has since been shown to be a safety hazard under supercritical conditions, initially investigators explored the use of nitrous oxide as an alternative to carbon dioxide to obtain alternative separation mechanisms. Excellent sensitivity was achieved, for example the limit of detection of bendicarb (S/N=5) was 3.8 ng . Carbamate pesticides were rapidly analysed with flame ionization detection by Wright and Smith. A single dermal dose of 2000 mg/kg caused clinical signs (fasciculations, decreased motor activity, hyperreactivity) in rabbits. with nitrous oxide as the mobile phase. In addition, several carbamates have been measured in serum and plasma. Despite the fact that dermal dosing is more germane to human exposure scenarios, the dermal NOELs, 1000 mg/kg for clinical signs in rats and rabbits, were not used as the basis for assessing the risks from acute exposure to propoxur. The high diffusivities of supercritical fluids allow for rapid equilibration, as the compounds of interest travel through the chromatographic column achieving higher separation factors in less time. Overall analysis times are therefore reduced. Due to the spherical symmetry, no oxygen diffusion occurs over the centre of the cell and we get the second boundary condition ∂Δc/∂r(t,0) = 0. (1) Nonoccupational exposures to office workers and home residents may occur through dermal contact with treated surfaces and, to a lesser extent, via inhalation of pesticide vapors. It does not have any food uses in the United States, but it is approved for crop use in the EU. The geometric mean exposure values used for the risk assessment are shown in Table 32.3. Sensitivity may occur after using ANY pesticide product for pets. Read the article on propoxur safety and/or on flumethrin safety in this site. A metabolite of propoxur, 2-isopropoxyphenol, was measured in urine samples collected from the study's participants. The human oral NOEL was used because (1) the use of human dose-response data eliminates the uncertainty associated with extrapolating to humans from laboratory animal studies and (2) the quality of the dermal toxicity studies was not comparable to the clinical observations in the human study. Product Name Kiltix Tick Collar for Dogs Product Use Insecticidal collar for tick control on dogs. Dashed: concentration difference between a point far away from the cell and the cell centre Δc(∞). This same effect on detector response was seen with the addition of methanol modifier to the nitrous oxide. Fill 975 μL of phosphate buffer (50 mM) pH 7.4 in an anaerobic cuvette with a microliter syringe. Propoxur, or Baygon, is an important carbamate insecticide used primarily against household insects and pests of domestic animals. In the human study, volunteers (number unstated) were reported to have exhibited cholinergic signs (stomach discomfort, blurred vision, moderate facial redness, and sweating) after a single bolus oral dose of 0.36 mg/kg. A single oral dose of 5 mg/kg resulted in cholinergic signs (muscle fasciculations) in dogs, but a dose of 4 mg/kg did not produce any signs. Thus, the measurement of 1-naphthol does not distinguish these two sources. A multichannel UV detector for capillary SFC was used to analyse the pesticides bendiocarb and carbaryl and the herbicides alachlor, diuron and metalaxyl. As was the case with ethoprop, the principal route of exposure for most pesticide applicators using propoxur is through the skin. Oxygen diffuses to the cell membrane, where it is either consumed by the terminal oxidases or diffuses further into the cell interior. A single dermal dose of 2000 mg/kg caused clinical signs (fasciculations, decreased motor activity, hyperreactivity) in rabbits. Dosing and administration: After opening the package, the … Toxic effects can be potentiated after simultaneous exposure to organophosphates or other synthetic pyrethroids. Nominal parameters of the reaction–diffusion model. Mean Acute Exposures to Propoxur and Their Respective MOSs. The studies and data, which formed the basis for estimating worker exposure, were based on passive dosimetry using patches attached to clothing. Pesticide Residues in Cocoa Shell and Nib. Concentrations of methanol above 0.8% resulted in a significant loss in signal from the detector. 508; Chemagro 9010; Dalf dust; EINECS204-043-8; ENT 25,671; HSDB 603; IPMC; Invisi-Gard; Isocarb; Mrowkozol; NSC379584; O-(2-Isopropoxyphenyl) N-methylcarbamate; OMS-33; PHC (carbamate); PHC 7; Phenol, o-isopropoxy-methylcarbamate; Propoksuru [Polish]; Propotox; Propoxure; Propoxylor; Propyon; Rhoden; Sendran; Suncide; Tendex; Tugon fliegenkugel; Unden (pesticide); o-IMPC; o-Isopropoxyphenyl N-methylcarbamate, Richard P. Pohanish, in Sittig's Handbook of Pesticides and Agricultural Chemicals (Second Edition), 2015. The buildup of plaque and tartar on the teeth and gums is the source of these diseases that today are the number one health problem for dogs. Creation Date 25th June 2003 Revision Date 9 December 2016 SECTION 2 – HAZARD IDENTIFICATION GHS-Classification Acute toxicity, Oral, Category 4 Hazardous to the aquatic environment, Category 1 Mortality was evident at 2000 ppm. Becker et al., 1996; Unden et al., 1995; Unden & Schirawski, 1997, Membrane Proteins—Production and Functional Characterization, Michael Lafontaine, C. Roy D. Lancaster, in, PESTICIDES | Supercritical Fluid Chromatography, Carbamate pesticides were rapidly analysed with flame ionization detection by Wright and Smith. Pre-reduce the quinone by adding 2.5–5 μL of a potassium borohydride solution (20 mg/mL). It is used to control cockroaches, flies, mosquitoes, and lawn and turf insects. The acid pesticides explored were 2,4-D, 2,3-D methyl ester, dicamba, piclotam, Silvex and Silvex methyl ester. The 95th percentiles of the absorbed cycle dosage for the respective work tasks were as follows: aerosol (1%) applicator, 2.30 μg/kg-cycle; bait (2%) applicator, 0.61 μg/kg-cycle; spray (0.95%) applicator, 0.32 μg/kg-cycle; and spray (70WP) applicator, 8.0 μg/kg-cycle. Measurement of other less abundant metabolites of carbaryl, such as 4-hydroxycarbarylglucuronide, may help to circumvent this problem. David A. Eastmond, Sharada Balakrishnan, in Hayes' Handbook of Pesticide Toxicology (Third Edition), 2010. Inhibition of AChE causes accumulation of acetylcholine in the synaptic cleft, with overt stimulation of cholinergic receptors of the muscarinic and nicotinic type. The recommended dosage is 1–2 g/m2, giving a residual effect of 3–6 months (World Health Organization, 2007a). The single-dose dermal NOEL for clinical signs was 1000 mg/kg in both rabbits and rats. Ethanol hand washes were collected to assess hand exposure, and air levels were monitored with personal pumps. Figure 2.8 shows the concentration differences between the cell centre and the inner side of the membrane Δc(R), the outer side of the membrane Δc(R + d) and the medium far away from the cell Δc(∞) for a variation of the model parameters away from their nominal value. Top 10 Best Tick Collars for Dogs 2020 1. The general rule for carbamates was that the ammonium adduct ion was the base peak. Propoxur is of moderate to low persistence in the soil (half-life of 14–50 days). However, in a series of studies conducted in rats, highly significant increases in hyperplasia and bladder tumors were seen at high doses of propoxur. The inactivation of FNR consumes oxygen that is not released upon its reactivation. Ces préparations pour animaux à sang chaud sont modérément toxiques et, à la dose recommandée, ne sont pas nocifs pour le chien. Iqbal R.F. The MOSs for mean acute exposure to propoxur, based on the human NOEL of 0.8 mg/kg for a 2-h period, ranged from 97 to 5000 (Table 32.3). The separated and identified carbamate pesticides were: aldicarb, aldicarb sulfoxide, aldicarb sulfone, carbaryl, BPMC, propoxur, chlorpropham, carbofuran, asulam, desmedipham, and penmedipham. The Indonesian MoH does not recommend this insecticide for IRS as part of its insecticide rotation cycle policy (Departemen Kesehatan, 2003c). Capillary SFC was used for sample introduction into the MS instrument. PROPOXUR JMPR 1973 IDENTITY Chemical name 2-isopropoxy-phenyl-N-methyl carbamate Synonyms PHC (common name in ... Groups of beagle dogs (four males and four females per group) were fed propoxur in the diet at concentrations of 0, 100, 250, 750 and 2000 ppm for two years. The WHO classifies it as a moderately hazardous chemical (World Health Organization, 2006b). However, in a series of studies conducted in rats, highly significant increases in hyperplasia and bladder tumors were seen at high doses of propoxur. Costa, in Encyclopedia of Toxicology (Third Edition), 2014. Concentrations of oxygen in the membrane are given as the according equilibrium concentration in an aqueous solution. The monitored activities in one location took 1.8 h to complete, which was rounded off to 2 h. This is defined as one cycle. (B) Disturbed parameter set Dcyt = 0.5Dcyt*, Dmem = 0.1Dmem*, Jtot = 2Jtot*, d = 10 ⋅ d*. Table 32.3. It was assumed that infants (6–9 months) had a body weight of 7.5 kg with 0.45 m. Acute MOSs were based on a 2-h human NOEL of 800 μg/kg for cholinergic signs. The absence of significant thermal degradation was indicated since the molecular species was present. Iqbal R.F. Elyazar, ... J. Kevin Baird, in, Handbook of Pesticide Toxicology (Second Edition), Geometric mean of one application—assumes that workers' body weights were 76 kg, dermal penetration was 0.351 %/h, and respiratory uptake was 50%. 1. : Never use on cats collars approved only for dogs. The half-life of propoxur in humans following intravenous administration was 8 hours. It was assumed that infants (6–9 months) had a body weight of 7.5 kg with 0.45 m. Acute MOSs were based on a 2-h human NOEL of 800 μg/kg for cholinergic signs. Avoid toxic chemicals in flea and tick collars, spot-on treatments, spray and other treatments. 2.6. Ce n'est qu'en contact avec les muqueuses qu'il peut provoquer une légère irritation. It is now possible to analyze the residue levels of the insecticides both in the nib and the shell separately; the results are compared with the analysis on the whole bean basis. LiChrosorb column. If used on pregnant or nursing dogs, do not replace collar until the puppies are at least 6 weeks old. It is a moderately toxic carbamate chemical. Propoxur is very mobile in sandy loam, silt loam and silty clay soils. With the exception of bait trays, additional risk-reduction measures … The separation of the thermally labile acid and carbamate pesticides propoxur, BPMC (fenobucarb), propachlor, carbofuran, alachlor, carbaryl, linuron, and diuron was achieved by Wright et al. Sergeant's Pet Care Products, Inc. and Wellmark International have agreed to stop producing pet collars containing the pesticide propoxur. The capillary column a 12 m×100 μm i.d. Mean Acute Exposures to Propoxur and Their Respective MOSs. The estimated 24-h absorbed dose of propoxur was based on the amount of the metabolite in the urine. The study used to estimate exposure to a pet owner for flea control on two dogs involved a biomonitoring study of 15 professional dog groomers who sprayed an average of 20 dogs during an 8-h workday. This shampoo allows you to provide regular care and of your pet’s coat. For people living in homes treated with crack-and-crevice treatments of propoxur for insect control, the exposures were calculated using default assumptions. Oxygen concentration in the membrane is underestimated by a factor of around 4.4. The geometric means of passive, nonoccupational exposures ranged from 2-h absorbed dosages of 0.22 to 1.4 μg/kg-day (Table 32.3). Then, the only spatial coordinate that we need to consider is the distance r from the centre of the cell. Propoxur is very mobile in sandy loam, silt loam and silty clay soils. Air concentrations in the home were more or less constant. In a rabbit developmental study, the maternal NOEL (1 day) was 10 mg/kg-day, based on cholinergic signs and death at 30 mg/kg. Unden and Schirawski (1997) and Unden et al. In a single-oral-dose neurotoxicity study, the LOEL for cholinergic signs (excessive chewing and reclining posture) and significant brain cholinesterase inhibition was 2 mg/kg-day. Storage: Propoxur at the rate of 0.94 g of active substance per 10 g of tape. Add 10 μL of a DMN solution (20 mM). We use cookies to give you the best possible experience on our website. Some of the carbamates, such as aldicarb, carbofuran, and propoxur, are commonly encountered in malicious poisonings in dogs and mammalian and avian wildlife. This mixture was further expanded with the addition of picloram and chloramben and baseline resolution was obtained on a 1.5 m capillary column in approximately 120 s, demonstrating consistently the rapid analysis times that can be achieved using SFC for carbamates. Propoxur is of moderate to low persistence in the soil (half-life of 14–50 days). Acetylcholine is a nerve system which sends messages between nerves. As a quinol is needed, the synthetic menaquinone analogon DMN has to be pre-reduced by the addition of small aliquots of a NaBH4 solution. Miller J E, Baker N F & Colburn E L Jr (1977)Insecticidal activity of propoxur- and carbaryl-impregnated flea collars against Ctenocephalides felis.Am J … The mean absorbed dose, normalized for two dogs, is presented in Table 32.3. The carcinogenic effects of propoxur in rats have been proposed to be due to chronic mitogenic stimulation of propoxur or a metabolite on the urothelium rather than from a direct genotoxic or mutagenic effect (Cohen et al., 1994). Analysis of the samples indicated a log-normal distribution of surface residues throughout the house. She - Answered by a verified Dog Veterinarian. Carbamate insecticides inhibit the cholinesterase activity of enzymes, causing accumulation of acetylcholine at synapses and altering the way in which nervous impulses are transmitted. No hyperplastic effects in the bladder were seen in short-term studies employing mice, dogs, or monkeys, whereas effects were seen in short-term studies in the bladders of Sprague–Dawley rats. My dog got into a propoxur roach bait station. The study used to estimate exposure to a pet owner for flea control on two dogs involved a biomonitoring study of 15 professional dog groomers who sprayed an average of 20 dogs during an 8-h workday. The MOS for the 95th percentile of the absorbed cycle dosage for dog owner/groomers was 13. With a skin irritation of propoxur, there may be evidence of redness of the skin, loss of fur, and a constriction of the iris of your pet’s eye. However, the preponderance of occupational or nonoccupational acute exposure to propoxur was through the dermal route (approximately 99% in most instances). After the collar had been secured by means of the buckle the loose end was passed through the retaining loop or loops. The mean absorbed dose, normalized for two dogs, is presented in Table 32.3. However, the preponderance of occupational or nonoccupational acute exposure to propoxur was through the dermal route (approximately 99% in most instances). A photodiode array spectrophotometer acquired the UV spectra. Thus in estimating the tolerance level permitted in raw cocoa beans (whole beans) an allowance should be made for the shell which makes up to 17% of the whole bean. Thus, the 30-min NOEL for cholinergic signs in humans following a single bolus dose was 0.2 mg/kg. The measurement is based on the quinol oxidation activity by simultaneous reduction of fumarate. Aldicarb, methomyl, diflubenzuron, and phenmedipham were baseline resolved in a little more than 20 min. Therefore, a closer, more microscopic view on oxygen diffusion and consumption is necessary and this is considered in the next section. Petcare Notix propoxur Shampoo for dogs 150ml is an excellent product to prevent ticks and fleas from your pet. Date of Listing: 08/11/2006. Roger C. Cochran, in Handbook of Pesticide Toxicology (Second Edition), 2001. Propoxur is a direct inhibitor of acetylcholinesterase (AChE), the enzyme that physiologically hydrolyzes the neurotransmitter acetylcholine. Acute effects: Eye, effects other than irritation; Skin irritant, moderate; Heart, cardiovascular system; Brain; Central nervous system; Nervous system toxin; Respiratory toxin, other than severe or moderate irritation; Nose, other than irritation. This suggests that the oxygen gradients may be in the order of 1–10% of the oxygen concentration. Try these safe natural flea and tick control treatments and methods for both dogs and cats. Propoxur is well absorbed into plant tissues and can thereby be active against insects for up to 1 month. Even though a single bolus dose of 0.36 mg/kg produced short-lasting stomach discomfort, blurred vision, moderate facial redness, and sweating, five oral doses of 0.2 mg/kg at 30-min intervals over a period of 2 1/2 h did not cause cholinergic signs. The monitored activities in one location took 1.8 h to complete. McNally, in Encyclopedia of Separation Science, 2000. Air concentrations in the home were more or less constant. Patches with nondetectable levels of propoxur were given default values equal to 50% of the MDL. Propoxur is a synthetic carbamate, aromatic ether compound, and acetylcholinesterase inhibitor that is used as a pesticide.It is characterized as a toxic, white to tan crystalline solid with a faint odor, and exposure occurs by inhalation, ingestion, or contact. Dana Boyd Barr, Brian Buckley, in Reproductive and Developmental Toxicology, 2011. In the rat, the LOEL (30 min) for cholinergic signs (convulsions, reduced motility, apathy, bristling coat) from a single oral dose was 25 mg/kg with a NOEL of 5 mg/kg. The largest concentration difference occurs if ξ is small that is if most of the oxygen is consumed in the cytoplasm and not at the membrane. Becker, Holighaus, Gabrielczyk, and Unden (1996) used an oxystat to analyse the effect of oxygen on FNR-dependent gene expression. She opened and ate some of a propoxur roach bait. For a set of nominal parameters (Table 2.3), a concentration difference of 0.02 μM is obtained. The carbamates, in general, are particularly unstable in blood so sometimes their metabolites must be measured as well. Additionally, carbamylated AChE does not undergo the aging reaction, as do organophosphate insecticides. Oral Spays developed for dogs to treat periodontitis and gingivitis that contain propolis have proven to be very effective. Inhibition of AChE occurs rapidly, as propoxur is a direct AChE inhibitor and does not require metabolic activation, but is transient and rapidly reversible, since there is rapid reactivation of the carbamylated enzyme in the presence of water. In this example, a biphenyl column was first in the series, a glyme column second. Acetylcholine is a nerve system which sends messages between nerves. Several processes are able to remove oxygen from the cell interior. By continuing you agree to the use of cookies. L. Charles Murrin, in xPharm: The Comprehensive Pharmacology Reference, 2007, Propoxur; 2-(1-Methylethoxy)phenol methylcarbamate ; 2-IsopropoxyphenylN-methylcarbamate ; 2-Isopropoxyphenyl-N-methylcarbamat [German]; 58 12 315; AI3-25671; Aprocarb; BAY 39007; BAY 5122; BRN 1879891; Bay 9010; Bayer 39007; Bayer B 5122; Baygon; Bifex; Blattanex; Blattosep; Bolfo; Boruho; Boruho 50; Brygou; CCRIS 1392; Caswell No. Documents, Presentations, and Publications; Cancer: Listing Notice - Doxorubicin Hydrochloride (Adriamycin) Aug 11, 2006 . To protect against adult fleas and ticks on dogs, collar should be replaced every 6 months or sooner if needed. The compounds investigated were, Environmental Toxicology and Pharmacology. Table 2.3. For example, Rolfe et al. Provides long-term protection for dogs from insects for 5 months, cats – for 4 months, from Ixodes mites – for 10 weeks. As absorption of propoxur via the dermal route is generally slower than absorption from the gut, decarbamylation, body metabolism, and clearance probably limit the effects of acute dermal exposure to propoxur. In a rabbit developmental study, the maternal NOEL (1 day) was 10 mg/kg-day, based on cholinergic signs and death at 30 mg/kg. By continuing to use this site you consent to the use of cookies on your device as described in our cookie policy unless you have disabled them. So, it is possible that the diffusion coefficients are overestimated and that the width of the membrane might need to be increased to include more than just the plasma membrane. For a growth rate of 0.15 h−1, Alexeeva (2000) reports an average oxygen concentration of about 1 μM in the region from 60% to 100% AU and a value of about 0.25 μM between 10% and 40% AU. Propoxur can affect you when breathed in and quickly enters the body by passing through the skin. Propoxur has yielded negative results in the majority of short-term genotoxicity tests that have been conducted (FAO/WHO, 1990). "Treated dogs had either 3 or 5 collars placed around their necks to achieve 3x and 5x the recommended use rated, respectively. (1995) compute the oxygen diffusion rate into E. coli cells and conclude that oxygen diffusion could only be limiting for FNR signalling at oxygen concentrations below 0.2 mbar. The acute NOEL for propoxur was based on human oral exposure leading to cholinergic signs. Indirectly, researchers have examined the correlation of the prevalence of 2-naphthol and 1-naphthol in order to discern the contributions of carbaryl and naphthalene exposure (Meeker et al., 2007). As was the case with ethoprop, the principal route of exposure for most pesticide applicators using propoxur is through the skin. Infants, 6–9 months of age, had the highest potential exposure. E. Owusu-Manu, in Pesticide Management and Insecticide Resistance, 1977. Fisch H, Angerhofer R A & Nelson J H (1977)Evaluation of a carbamate-impregnated flea and tick collar for dogs.JAVMA171(3), 269-270. The total oxygen consumption of the cell is given by Jtot (mol/s). Table 32.3. For ξ = 0.75, a total concentration difference of 0.1 μM is reached wherefrom a considerable part occurs in the membrane region. Propoxur has been used in malaria control activities and in flea collars for pets. The NOELs for clinical signs (specified amounts—up to 1 mg/kg—for specific lengths of time—up to 2 1/2 h) were used to evaluate the health risks from potential acute exposures of different durations to propoxur. For adults, the assumptions were 76 kg body weight, 2.0 m2 surface area, and 1 m3/h breathing rate. Propoxur did not accumulate in any body tissues, with the exception of the kidney during the process of excretion. Other Names Flumethrin, Propoxur. Consequently, the dose-response data of adverse effects observed in short-term dermal toxicity studies were the initial choice as the basis for calculating margins of safety for workers with short-term exposure to propoxur (Cochran et al., 1997). Again, capillary SFC was used as a means of sample introduction. The model does not account for the unequal equilibrium partition of oxygen between a lipid phase and an aqueous solution. LD50 (oral, rat) = < 50 mg/kg; LD50 (dermal, rat) = > 5 g/kg. In chronic studies, no evidence of carcinogenic effects was seen in mice treated with propoxur for 24 months or hamsters treated for 53 weeks (FAO/WHO, 1990).
