Protective effect of Eleteria cardamomum(L.) Maton against Pan masala induced damage in lung of male Swiss mice

Objective:To study the potential ameliorating properties of cardamom Elettaria cardamomum (E.cardamomum) L.Maton against pan masala induced damage in lung of male Swiss mice. Methods:The experimental animals were divided into 3 groups(control,pan masala treated group and pan masala with cardamom treated group) to evaluate pan masala toxicity.The observations were substantiated with profound changes in the lung tissue as revealed in the histologic and transmission electron microscopic examinations.Results:Lung of pan masala treated group showed adenocarcinoma,edema,and inflammation with increased activity of acid phosphatase,alkaline phosphatase,and lactate dehydrogenase.The deleterious effects were seen to be less in cardamom treated group and the enzymatic activity also decreased significantly (P【0.05)\ in the ameliorating group.Conclusions:Thus,the present experiment exciting results are observed when cardamom is supplemented with pan masala,or when given alone.

Histological and ultrastructural studies on the toxic effect of pan masala and its amelioration by Elettaria cardamomum

AIM:To investigate the histological and ultrastructural changes observed in pan masala intoxicated mammalian testes under the effect of cardamom.METHOD:Male Swiss mice were given pan masala orally at a dose of 2% of the feed and cardamom at a dose of 0.2% of the feed.They were divided into three groups,control(Group I),pan masala-treated(Group II),and a combination of pan masala and cardamom-treated group(Group III).Histologically,the testes of Group II mice displayed degeneration of tubular epithelium,disruption of spermatogenesis,and a marked reduction in germ cells.RESULTS:When cardamom was given,damage was less with fewer distorted cells and also improvement with normal tubules and spermatid differentiation in Group III.Ultrastructurally,pan masala-treated testes showed cytoplasmic vacuolation,shrinkage and pyknotic nuclei of spermatogonia,and abnormal acrosomal granules.CONCLUSION:When cardamom was given,the amelioration process was more evident showing a comparable morphology with control.

The diurnal activity, movement and trypanosome infection rates of Glossina fuscipes fuscipes （Diptera： Glossinidae） in Buvuma Island, Lake Victoria, Uganda

The diurnal activity patterns, trypanosome infection rates and movement of Glossinafuscipesfuscipes （Diptera： Glossinidae） were investigated in Buvuma Island, Lake Victoria, Uganda. Hourly trapping of tsetse flies was undertaken to determine their activity rhythm while a capture-mark-release-recapture method was conducted to assess the movement and dispersal of tsetse flies between lakeshore, hinterland and further inland sites along a transected area. Dissection of tsetse flies was also undertaken to determine the trypanosome infection rates in salivary glands, proboscis and mid-gut. Results indicated a bimodal diurnal activity profile for G. f fuscipes on the Island, both on the lakeshore and in the hinterland. Movement and dispersal of G. f fuscipes tsetse flies occurred between lakeshore, hinterland and further inland sites with a greater tendency of flies to move to the lakeshore. Trypanosome infection rates of 4.32% for Trypasoma vivax and 1.15% for 7. congolense were found in G. f. fuscipes.
