ABSTRACT
Hexane extract of male terminalia (along with scent brushes) of castor semi-looper moth, Achaea janata L, elicited significant olfactory responses in both male and female insects by electroantennogram recording technique. However, male extract in the wind tunnel evoked noticeable behaviour responses in the female insects only. Orientation response of the males to the male extract was not evident in wind tunnel experiments. Two electrophysiologically-active compounds were identified from the male extract. Based on GC retention times and mass spectrometry the two compounds were confirmed as (Z,Z)-9,12-octadecadienal and (Z,Z,Z)-3,6,9-heneicosatriene. These two compounds are also constituents of female produced four-component blend of A. janata.

Bile Cultures for aerobic and anaerobic bacteria were carried out on 125 samples from patients with chronic cholecystitis with cholelithiasis. Cultures grew 71(56.8%) aerobes and 17(13.6%) anaerobic microorganisms. Polymicrobial infection was seen in 7(16.2%) cases. E. coli (45.07%) and Klebsiella (25.35%) were predominant among the aerobes and Bacteroides fragilis (58.82%) was predominant among the anaerobes. Highest incidence of the disease was observed in the fourth decade of life and females predominated in this study.
