ABSTRACT
A cross-sectional observational study was carried out between April to May 2006 by interview method and observation technique with the objective to know the knowledge regarding hand washing in the community and it was done in the slum and nonslum urban areas and also one rural area. The result shows that in urban slum area 98% washed their hands with soap after defecation; Only 36%, 16% and 2% washed their hands with soap before meal, before serving food and before cooking respectively. However, it was observed that 69% used soap and water for hand washing after cleaning the child's faeces. In rural area 71% used soap and water after defecation while 26% used mud or ash. Only 13%, 1%, 1% and 5% used soap and water before meal, before serving food, before cooking and after cleaning the child's faeces. 82.35% of respondents in non slum area and 89% of respondents in rural area considered that diarrhoea and dysentery could be prevented by hand washing while they did not give importance to hand washing in prevention of diarrhoea over other methods like cleanliness, boiling and purification of water. ARI was much higher (25.72%) in rural area followed by slum area (13.77%) and non-slum area (3.87%). Out of 30 observations among 302 interview made on hand-washing only first step i.e. palm washing (transient rubbing the palm with soap) was followed by all the participants observed. Time taken for such hand-washing was only around five seconds (ideal 15-30 seconds) in urban slum and rural areas while in non slum area it varied between 7-10 seconds on an average. No one followed any other steps of hand-washing, recommended by IFH.

A 50-year-old male attended outpatients department with complaints of irritation, foreign body sensation and mild redness in his right eye. On examination a conjunctival nodule was found with localised inflammation. All investigations were normal. Surgical excision of the nodule was contemplated. During local dressing a live tapeworm about 20 cm in length and 3 mm in breadth emerged. Pathological examination confirmed it to be a tapeworm spirometra. The case was diagnosed to be ocular sparganosis.

A haemorrhagic toxin (VRR-12) from Vipera russelli russelli (Russell's viper) venom has been purified by ion-exchange chromatography on CM-Sephadex C-50 followed by size-exclusion HPLC to electrophoretically homogeneous state. It is a 12 kDa single polypeptide having 1 mole of Zn+2 ion. This toxin induces intense intestinal haemorrhage and to a lesser extent skeletal muscle haemorrhage in mice. It does not show detectable proteolytic and esterolytic activity with selected substrates under specified conditions, haemolytic and phospholipase activity. When VRR-12, preincubated with bivalent antiserum against Saw-scaled and Russell's viper venom or EDTA was injected, haemorrhagic activity was not reduced, on the other hand preincubation with phenylmethyl sulphonyl fluoride reduced the activity markedly. Biodistribution studies with 125I VRR-12 show that haemorrhagic manifestation by this toxin is not a direct function of the fraction of the totally administered toxin distributed to that tissue.

In a model experiment, seed extracts were applied to different bacterial test organisms. Different fractions of seed extracts in petroleum ether (60-80 degrees C) of Lagerstroemia speciosa (Linn. ex. Murray) Pers. when applied to both Gram positive and Gram negative test bacteria, some fractions showed high antagonistic activity.

Lethal and haemorrhagic activity of Russell's Viper venom was compared against polyvalent bivalent commercial antiserum and monovalent antiserum raised in rabbit. Formaldehyde-detoxified venom offered 7-fold protection against lethal activity and 12.5-fold against haemorrhagic activity of the venom. Whole venom and formaldehyde-detoxified venom along with Freund's complete adjuvant, injected in rabbits produced high titre antiserum. Amongst all the six antiserum tested, the monovalent antiserum raised in rabbit, showed maximum precipitating bands in immunogeldiffusion and immunoelectrophoresis. The toxoid-antiserum offered maximum protection against the venom-induced lethality and the monovalent antiserum offered maximum protection against haemorrhagic activity.
