A study was carried out in theJengka Triangle in Pahang to find out the prevalence and a practical cum effective method of treatment and control of scabies. Scabies was the commonest skin lesion among the 5590 people examined. its prevalence being 11.6%. Both sexes were equally affected. Prevalence was high among children and teenagers, the worst affected being the 10 to 14. 2 to 4, 15 to 19 and 5 to 9 year olds. The problem of scabies in Jengka could be due to inadequate and irregular water supply, plus lack of mothers' supervision of the personal hygiene of their children aged > 2 years. The persistence of scabies since 1976 is very likely due to the people's non-compliance with standing instructions on treatment with Benzyl benzoate emulsion A comparative study of treatment of scabies with Gamma Benzene Hexachloride [GBH] and with Benzyl benzoate emulsion [BBE] showed GBH to be the medication of choice. It was more effective and convenient, giving 97.9% cure rate with one application. A hot bath was not necessary. The patients preferred GBH to BBE since it was painless and without side-effects. The cost of treatment with GBH [1 application] was also much less than that with BBE [2 applications]. Only 28.7% of the cases and contacts complied with instructions to do 2nd application of the medication on their own, making it imperative that application be done by the health Staff or under their direct supervision. The majority [87.2%] complied with instructions to place their used clothes in large polythene bags and air these in the sun for two days. This procedure should replace the instructions to boil personal clothes as it is just as effective. yet more convenient and economical. A regular, biannual screening of all kindergarten and primary school children is recommended. Application of GBH to all scabies cases and all close contacts should be done by the health worker. The whole body from neck to soles of feet should have the application, and the people should be instructed to bathe only after 24 hours. They are to go to the nearest clinic or hospital on the 7th day for second application of GBH, if the itchness or lesions persist or reappear. Such supervised medication is possible and will minimise misuse of GBH.
Indolic compounds have attracted a lot of attention due to their interesting biological properties. The present study was performed to evaluate the subacute toxicity and anti-ulcer activity of BClHC against ethanol-induced gastric ulcers. Experimental animal groups were orally pre-treated with different doses of BClHC (50, 100, 200 and 400 mg/kg) in 10% Tween 20 solution (vehicle). Blank and ulcer control groups were pre-treated with vehicle. The positive group was orally pretreated with 20 mg/kg omeprazole. After one hour, all groups received absolute ethanol (5 mL/kg) to generate gastric mucosal injury except the blank control group which was administered the vehicle solution. After an additional hour, all rats were sacrificed, and the ulcer areas of the gastric walls determined. Grossly, the ulcer control group exhibited severe mucosal injury, whereas pre-treatment with either derivative or omeprazole resulted in significant protection of gastric mucosal injury. Flattening of gastric mucosal folds was also observed in rats pretreated with BClHC. Histological studies of the gastric wall of ulcer control group revealed severe damage of gastric mucosa, along with edema and leucocytes infiltration of the submucosal layer compared to rats pre-treated with either BClHC or omeprazole where there were marked gastric protection along with reduction or absence of edema and leucocytes infiltration of the submucosal layer. Subacute toxicity study with a higher dose of derivative (5 g/kg) did not manifest any toxicological signs in rats. In conclusions, the present finding suggests that benzyl N'-(5-chloroindol-3-ylmethylidene)hydrazinecarbodithioate promotes ulcer protection as ascertained by the comparative decreases in ulcer areas, reduction of edema and leucocytes infiltration of the submucosal layer.
