Effects of whole Lemon grass (Cymbopogon citratus) extract on bacteria (Aeromonas veronii) infected Sub-adult Clarias gariepinus

The lemon grass, Cymbopogon citratus (DC) Stapf, is an important species of Poaceae family commonly used in the folk medicine in many countries. The aim of this study was to investigate the cytotoxic and genotoxic effects of aqueous extracts from C. citratus leaves on Lactuca sativa (lettuce) root tip meristem cells by cytogenetic studies that have never been done before for lemon grass extracts. For this, lettuce seeds were treated for 72h with different concentrations of lemon grass aqueous extracts (5; 10; 20 and 30 mg/mL). The percentage of germination, root development and cellular behavior were analyzed, and the results showed that the highest concentration of aqueous extracts reduced the mitotic index, the seed germination and the root development of lettuce. The extracts have also induced chromosome aberrations and cellular death in the roots cells of L. sativa.

Albino Mice

Background: Depression is a common psychiatric disorder. Drug therapy is the cornerstone in the management of depression. Anti-depressants are associated with many unwanted side-effects. Thus, various herbal products have been tried. The advantages of herbal treatments include safety, cheap and acceptability due to their traditional values. The objective of the present study was to evaluate the anti-depressant activity of Cymbopogon citratus (lemon grass) in albino mice and to compare with Imipramine. Methods: 30 Swiss albino male mice weighing around 25-30 g were divided into 5 groups (n=6). Group I (Control) mice were given normal feed and water, Group II (Standard) received 20 mg/kg T. Imipramine orally, Group III (Test-1) received 5 mg/kg aqueous extract of C. citratus (lemon grass) orally and Group IV (Test-2) received 10 mg/kg C. citratus (lemon grass) orally, and Group V (Test-3) received both T. Imipramine (10 mg/kg) and C. citratus (10 mg/kg) orally. Duration of immobility was observed for last 4 mins of total 6 mins period in groups 1-5 by tail suspension test on 1st, 8th and 15th day.Results: Duration of immobility recorded in seconds was analyzed by one-way analysis of variance, followed by Tukey’s post-hoc test Conclusion: Lemon grass has a significant antidepressant effect. Combined effect of lemon grass at 10 mg/kg and imipramine 10 mg/kg is not synergistic.

This study was carried out to determine the effect of lemon grass marinade (sample A), bay leaf marinade (sample B) and a combination of both spices (sample C) on the microbial load of stored smoked-dried Clarias gariepinus. Comparative analysis of the microbial load of each treated fish samples during ambient storage was done biweekly for six (6) weeks and then samples of each treatment were taken to the laboratory periodically. The fish samples were analysed using Potato Dextrose Agar and Nutrient Agar for fungi and bacteria respectively. The initial microbial load before storage showed that the highest number of bacteria counts occurred in smoke-dried Clarias gariepinus treated with bay leaf marinade (4.7´103) while the lowest was in smoke-dried C. gariepinus treated with lemon grass marinade (1.3´103). The highest fungi count was observed in smoke-dried C. gariepinus treated with the combination of both spices (9.5´102) while the least fungi count was in fresh fish sample (1.4´103), although the fresh fish sample had the highest bacteria mean count (5.1´103) when compared with the treated samples. After 6 weeks of ambient storage, the result of smoke-dried C. gariepinus treated with bay leaf marinade was also significantly different from the mean population of smoke-dried C. gariepinus treated with lemon grass marinade and smoke-dried C. gariepinus treated with the combination of both spices. Smoke-dried C. gariepinus treated with bay leaf marinade again had the highest bacteria and fungi mean count of 1.7´105 and 2.3´104 respectively. Smoke-dried C. gariepinus treated with lemon grass marinade and smoke-dried C. gariepinus treated with the combination of both spices had similar bacteria mean count of 1.5´105 while smoke-dried C. gariepinus treated with lemon grass marinade had the lowest fungi mean count of 1.6´104. The study revealed that all three smoked-dried fish sample treatment had a relatively low bacterial and fungal count below the 5 x 105cfu/g recommended by the International Commission of Microbial Specification for Food and Food Products (ICMS, 2002).
