The inhibitory effect of Cannabis Sativa L. and Morus nigra L. against lipid peroxidation in goat liver and brain homogenates / O efeito inibitório de Cannabis Sativa L. e Morus nigra L. contra a peroxidação lipídica em homogenatos de fígado e cérebro de cabra

The present study was aimed to evaluate the antioxidant potential and inhibitory effect of Cannabis sativa and Morus nigra against lipid peroxidation in goat brain and liver homogenates. The formation of free radicals, highly reactive oxygen species (ROS) and reactive nitrogen species (RNS) is a normal metabolic process for cellular signaling and countering the antigens. However, they may cause serious damage if they produced at amplified tolls. In addition, metabolic disorders also serve as sources of these reactive species. Although the issue can be addressed through supplements and other phytochemicals. In this study, two plant species were evaluated for their biological potential by employing a spectrum of antioxidant assays. The antioxidant activity was performed by lipid peroxidation assay. The water extract prepared from leaves of Cannabis sativa and Morus nigra showed significant (P<0.05) inhibition as compared to control i.e., 522.6±0.06 and 659.97±0.03 µg/mL against iron-induced lipid peroxidation in goat brain homogenate while the inhibitions were 273.54±0.04 and 309.18±0.05 µg/mL against nitroprusside induced lipid peroxidation of the brain. The iron and nitroprusside induced lipid peroxidation was also significantly inhibited by leaf extracts of Cannabis sativa and Morus nigra in liver homogenates such as 230.63±0.52 and 326.91±0.01 µg/mL (iron-induced) while 300.47±0.07 and 300.47±0.07 µg/mL (nitroprusside induced), respectively. The extracts of Cannabis sativa extract showed promising activity (96.04±0.060%) against DPPH radicals while Morus nigra showed a moderate activity (34.11±0.120%). The results suggest that different accessions of Cannabis sativa and Morus nigra are a potential source of antioxidants and have a therapeutic effect against disease induced by oxidative stress and hence can be used for novel drug discovery and development.

Study of resveratrol against bone loss by using in-silico and in-vitro methods / Estudo do resveratrol contra a perda óssea usando métodos in silico e in vitro

By applying the in-silico method, resveratrol was docked on those proteins which are responsible for bone loss. The Molecular docking data between the resveratrol and Receptor activator of nuclear factor-kappa-Β ligand [RANKL] receptors proved that resveratrol binds tightly to the receptors, showed the highest binding affinities of −6.9, −7.6, −7.1, −6.9, −6.7, and −7.1 kcal/mol. According to in-vitro data, Resveratrol reduced the osteoclasts after treating Marrow-Derived Macrophages [BMM] with Macrophage colony-stimulating factor [MCSF] 20ng / ml and RANKL 50ng / ml, with different concentrations of resveratrol (2.5, 10 μg / ml) For 7 days, the cells were treated with MCSF (20 ng / ml) and RANKL (40 ng / ml) together with concentrated trimethyl ether and resveratrol (2.5, 10 μg / ml) within 12 hours. Which, not affect cell survival. After fixing osteoclast cells with formaldehyde fixative on glass coverslip followed by incubation with 0.1% Triton X-100 in PBS for 5 min and after that stain with rhodamine phalloidin staining for actin and Hoechst for nuclei. Fluorescence microscopy was performed to see the distribution of filaments actin [F.actin]. Finally, resveratrol reduced the actin ring formation. Resveratrol is the best bioactive compound for drug preparation against bone loss.

Com a aplicação do método in-silico, o resveratrol foi ancorado nas proteínas responsáveis pela perda óssea. Os dados de docking molecular entre o resveratrol e o ligante do receptor ativador do fator nuclear kappa-Β [Receptor Activator of Nuclear Factor kappa-B Ligant (RANKL)] provaram que o resveratrol se liga fortemente aos receptores, mostraram as afinidades de ligação mais altas de −6,9, −7,6, −7,1, −6,9, - 6,7 e -7,1 kcal / mol. De acordo com dados in-vitro, o resveratrol reduziu os osteoclastos após o tratamento de macrófagos derivados da medula óssea [Bone Marrow derived Macrophage (BMM)] com fator estimulador de colônias de macrófagos [Macrophage Colony-Stimulating Factor (MCSF)] 20ng / ml e RANKL 50ng / ml, com diferentes concentrações de resveratrol (2,5, 10 μg / ml). Durante sete dias, as células foram tratadas com MCSF (20 ng / ml) e RANKL (40 ng / ml) juntamente com éter trimetílico concentrado e resveratrol (2,5, 10 μg / ml) em 12 horas, processo que não afeta a sobrevivência celular. Após a fixação de células de osteoclastos com fixador de formaldeído em lamela de vidro seguido de incubação com 0,1% Triton X-100 em PBS por 5 min, foi realizado posteriormente o procedimento para corar com rodamina faloidina a actina e Hoechst os núcleos. A microscopia de fluorescência foi realizada para ver a distribuição dos filamentos de actina [F.actina]. Finalmente, o resveratrol reduziu a formação do anel de actina. O resveratrol é o melhor composto bioativo para o preparo de medicamentos contra a perda óssea.

Congenital CMV infection; diagnosis in symptomatic infants.

Background: Samples from babies exhibiting clinical symptoms suggestive of congenital infection are referred regularly to NICD, New Delhi,, from Government Hospitals located in Delhi and a home for abandoned children (Palna), for the diagnosis of etiological agents like toxoplasma, rubella, CMV and herpes. Blood samples of mothers of most of the affected babies are also received. Objective: Evaluation of rapid and accurate technique for the diagnosis of congenital CMV infection. Materials and Methods: One hundred and twenty five blood samples suggestive of symptomatic congenital CMV infection were selected from samples received at NICD during the period June 2005-March 2007. A request to collect and send the urine samples of the selected babies was sent to the respective hospitals. Serum samples of the babies were tested for CMV-IgM antibodies using µ-capture ELISA. Mothers' serum samples were subjected to CMV-IgM and IgG class antibodies assay by commercial ELISA kits. DNA isolation and amplification was performed in urine samples and some of the serum samples using a commercial PCR kit for detection of HCMV. Blood and urine samples from 20 normal babies were included in the study. Results: Twenty Seven serum samples (21.6%) of infants, of the 125 tested, were positive for CMV-IgM antibodies. Twenty five samples (20%) showed amplification of CMV -DNA. All 25 samples positive for PCR were positive for CMV IgM antibodies. Sera of 73 mothers, out of 75 tested (97.3%), were positive for CMV IgG antibodies. However, none of them was positive for CMV IgM antibodies. Mothers of all 27 positive babies were positive for CMV-IgG antibodies. Serum and urine samples from 20 normal babies were negative for ELISA and PCR. Conclusion: µ-capture ELISA technique was found to be more sensitive than PCR (92.6%) for detection of congenital CMV infection. ELISA is also rapid, less cumbersome and cost effective for diagnosis of CMV infection.

Carcinoma-rectum in an 11 years old boy.

Carcinoma rectum is a very uncommon malignancy in childhood. The incidence of colon cancer is found to be 1.3 cases per million children. An eleven years old boy with carcinoma rectum was admitted in the Department of Paediatric Gastroenterology, Bangabandhu Sheikh Mujib Medical University (BSMMU). The boy presented with irregular fever, altered bowel habit, poor appetite, gradual weight loss and abdominal pain. His abdomen was tender with no organomegaly. The rectal wall was tender and hard mass could be felt in the surrounding area on direct rectal examination. Diagnosis was confirmed by biopsy of the tissue from the growth. Surgical resection and anastomosis was done. After one month of surgery chemotherapy was started. Since carcinoma rectum in children has not been reported in Bangladesh we share the information with professionals.

Eminent ayurvedic physicians of Nizam dynasty.

It is a biographical work which sheds light on the lives and works of some of the Ayurvedic Physicians flourished during Nizam dynasty. The credit for development of Ayurveda in Hyderabad goes to the eminent Ayurvedic Physicians, mentioned in this articles who taught Ayurveda in their private clinics, rendered their services during the outbreak of epidemics, organised conferences, compiled very useful works on Ayurveda and established an Ayurvedic school on a grand scale which was recognised by the government.

A brief history of Ayurveda in Hyderabad.

This article contains a brief history of Ayurveda in Hyderabad. It can be proudly stated that this system is prevailing here since foundation of this city in 1590 A.D. As it is said that the physicians of Ayurveda and Unani both were among the staff of the first general hospital of Hyderabad city 'Darush-shifa' which was constructed in 1595 A.D. After the Qutub Shahi period the rulers of Asafjahi dynasty also patronised this system. The physicians of this period not only run their clinics but they also teach this system to their pupils privately. Due to the efforts of some eminent Ayurvedic physicians, Ayurveda progressed well. The names and the photos of these physicians have been given in this article. Now this system has a good status here with well established college, hospital and research department etc.

Prediction of airway responsiveness to allergen from skin sensitivity to allergen, airway responsiveness to histamine and serum IgE levels.

Immediate allergic reaction of the skin, non allergic airway responsiveness of the bronchi, and serum IgE levels were estimated in 25 atopic non asthmatic subjects and 15 controls. A good correlation was observed between these three parameters i.e. patients with positive skin response to allergen had increased airway responsiveness and significantly increased levels of serum IgE. However, the serum levels of IgE provided a significantly better indication of the likely presence of bronchial allergic reactivity than did the skin reactivity. The results indicate that knowledge of the airway responsiveness to histamine, skin sensitivity to allergen and serum IgE levels can predict the presence of airways responsiveness to an allergen. In all atopic non asthmatic individuals with a significant correlation between these parameters, the relevant allergen could stand identified as having the potential to provoke attacks of clinical asthma.
