The humoral immune response of chicken vaccinated with fowl and pigeon pox virus vaccines was determined with the protective potentiality of the two vaccines in field condition of Bangladesh. Different aged Fayoumi chicks were subjected for the study. To assess the relationship with better immune response among experimental groups, the average percentage of ``take reaction`` was examined and recorded to 97.77% in group A, 93.33% in group B and 100.0% in group C. The level of immune status induced by different vaccinated group was measured by passive hemaggluti?nation(PHA) microplate test method. The mean PHA titer levels after primary vaccination were 33.06±14.13 in group A, 32.0±14.81 in group B, and 33.0±13.66 in group C. Following booster vaccination, the mean PHA titer levels in prior of challenge were increased to 55.46±14.64 in groups A and C, and 46.93±16.52 in group B. The recorded PHA titer levels of each group at two weeks after challenge were significantly increased to 106.66±31.22, 93.86±33.04 and 110.93±29.29, respectively. The PHA titer levels after vaccination and challenge were significantly increased compared to pre?vaccination titer levels(P<0.01). Although the PHA titer levels among three groups administrated different vaccine combinations in prior of challenge were significantly varied(P<0.01), it was observed that all of the vaccinated chicks were highly protected against challenge infection.

MA Hannan,MA Hossain,MT Islam 경희대학교 융합한의과학연구소 2010 Oriental Pharmacy and Experimental Medicine Vol.10 No.2

The seed powder of Abrus precatorius L. has traditionally been used as oral contraceptive agent by the women in some rural areas in Bangladesh. The present study aimed to examine the antifertility activity of A. precatorius seed extracts in experimental female rats. Finely ground seeds were extracted with aqueous acetone followed by successive partitioning with n-hexane, ethyl acetate (EtOAc), methanol (MeOH) and water. Water suspended crude seed powder, organic fractions of acetone extract and a standard contraceptive drug (Nordette®28) were separately administered orally to the female rats for 30 days. n-Hexane, EtOAc and MeOH solubles at the doses of 2, 4 and 6mg/rat/day, respectively and crude seed powder at 100 mg/rat/day exhibited 100% antifertility activity with lowest levels of serum luteinizing hormone (LH), follicle stimulating hormone (FSH)and 17β-estradiol. Histological study of ovary and uterus of these rats exhibited reduced number of developing follicles and increased number of atretic follicles in the ovary, and fewer uterine glands with shrunken morphology, reduced endometrial height, poor vascularity and compact stroma in uterus. However, the activities of serum glutamate oxaloacetate transaminase and serum glutamate pyruvate transaminase and the body weight of the rats remained almost unaffected in all the seed extract treated rats compared to control. These results suggest that A. precatorius seed extracts reduced the levels of serum FSH, LH and 17β-estradiol probably by affecting hypothalamic-pituitary-gonadal axis. The reduced levels of these hormones might have affected the oestrous cycle, follicular development, and subsequently the establishment of pregnancy in treated rats.

Occupational Lifting Tasks and Retinal Detachment in Non-Myopics and Myopics: Extended Analysis of a Case-Control Study

Mattioli, Stefano,Curti, Stefania,De Fazio, Rocco,Mt Cooke, Robin,Zanardi, Francesca,Bonfiglioli, Roberta,Farioli, Andrea,Violante, Francesco S. Occupational Safety and Health Research Institute 2012 Safety and health at work Vol.3 No.1

Objectives: Lifting heavy weights involves the Valsalva manoeuvre, which leads to intraocular pressure spikes. We used data from a case-control study to further investigate the hypothesis that occupational lifting is a risk factor for retinal detachment. Methods: The study population included 48 cases (patients operated for retinal detachment) and 84 controls (outpatients attending an eye clinic). The odds ratios (OR) of idiopathic retinal detachment were estimated with a logistic regression model (adjusted for age, sex and body mass index). Three indexes were used to examine exposure to lifting; 1) maximum load lifted, 2) average weekly lifting, 3) lifelong cumulative lifting. Results: For all indexes, the most exposed subjects showed an increased risk of retinal detachment compared with the unexposed (index 1: OR 3.57, 95% confidence interval [CI] 1.21-10.48; index 2: OR 3.24, 95% CI 1.32-7.97; index 3: OR 2.23, 95% CI 1.27-8.74) and dose-response relationships were apparent. Conclusion: These results reinforce the hypothesis that heavy occupational lifting may be a relevant risk factor for retinal detachment.

Enhanced anti-inflammatory activity of curcumin, a naturally occurring pigment in turmeric via cyclodextrin complexation

Kohli, K,Ali, J,Najmi, AK,Anwer, MT,Ansari, MJ Kyung Hee Oriental Medicine Research Center 2007 Oriental pharmacy and experimental medicine Vol.7 No.2

Curcumin, a dietary pigment responsible for the yellow color of curry, has been used for the treatment of inflammatory diseases and exhibits a variety of pharmacological effects such as anti- inflammatory, anti-tumor, anti-oxidant, and anti-viral activity. In order to examine the potency of the curcumin in inflammation we used carrageenan induced rat hind paw odema model. As curcumin is practically water insoluble, it is hypothesized that pharmacological activity of curcumin could be improved by enhancing its water solubility. Water soluble complexes of curcumin with cyclodextrins were prepared and screened for greater solubility. Pure curcumin 100 mg/kg body weight along with curcumin complexes equivalent to 100 mg/kg body weight of pure curcumin were tested for the anti-inflammatory activity in Wister rats male rats using carrageenan induced hind paw edema model and compared with that of the reference compound diclofenac sodium at a dose level of 10 mg/kg body weight. Results were statistically analyzed using ANOVA. All the treatment groups showed statistically significant anti-inflammatory activity compared with that of vehicle control and positive control.

Ahmed, Firoj,Shahid, IZ,Razzak, MA,Rahman, M Mostafizur,Hoque, Tahmina,Rahman, MT,Sadhu, SK Kyung Hee Oriental Medicine Research Center 2006 Oriental pharmacy and experimental medicine Vol.6 No.1

The crude alcoholic extracts of various parts of five different Bangladeshi mangrove plants (Amoora cucullata, Caesalpinia bonducella, Cerbera odollam, Derris uliginosa and Sonneratia caseolaris) were screened in-vitro for anti-oxidant activity using the 1,1-diphenyl-2-picryldydrazyl-hydrate (DPPH) free radical scavenging assay. Of all of them, the ethanolic extracts of the leaves of Derris uliginosa and Sonneratia caseolaris showed potential antioxidant activity ($IC_{50}$: 94.406 and 26.30 mg/ml respectively) whereas the ethanolic extracts of aerial parts of Derris uliginosa, barks of Cerbera odollam and leaves and stems of Caesalpinia bonducella showed moderate activity ($IC_{50}$: 125.89, 211.35 and 301.99 mg/ml respectively). Mild anti-oxidant activity was observed with the methanolic extract of leaves of Amoora cucullata and ethanolic extracts of fruits of Cerbera odollam.
