ABSTRACT
Malaria parasite requires a specific time to replicate and disseminate in the mosquito's body before transmission to naïve hosts can occur. Vector control has a proven record in the prevention and control of malaria. The evaluation of vector control strategies requires accurate methods of predicting mosquito age. Anopheles stephensi is the principal malaria vector of the desert part of India. The objective of this study was to correlate the age of laboratory reared and field collected adults of An. stephensi with the glucose-6-phosphate dehydrogenase (g6pd) activity. The measurement of g6pd activity was carried out in a UV-vis spectrophotometer. The g6pd activity in the males and females An. stephensi was inversely proportional to their age. A significant correlation of the g6pd activity was recorded between the field collected and laboratory reared mosquitoes. The g6pd activity in the males An. stephensi was found to be significantly higher than the females. The finding of the present study is useful for the prediction of the age of males and females An. stephensi.

Eight patients of choledochal cyst have been diagnosed and six have been managed surgically. There were two children and six adults. Both the children had Type I cyst. They were managed by excision of the cysts. One lady with associated stone and carcinoma of the gall bladder underwent radical cholecystectomy with excision of segments IV and V of liver. Second lady with intrahepatic porcelain gall bladder had a choledochocele and was treated by transduodenal sphincteroplasty. Fifth patient, an 82 years old man with symptomatic gall stone with Type I choledochal cyst was subjected to just a cholecysto-jejunostomy. A 54 years old man with a Type IV cysts has undergone excision of the cyst. In patients undergoing excision of choledochal cysts, the biliary tract was reconstructed by a Roux-en-Y hepaticojejunostomy. Two of our patients never turned up for surgery. All the operated patients were asymptomatic during the follow-up period of 6 months to 24 months.
