Tuberculosis is a major health issues worldwide. Every year more than 9 million new cases are reported worldwide with death rate of around 2 million each year. Rapid and accurate diagnosis of tuberculosis in population is most supportive in proper medication and early recovery. The golden standard method for diagnosis of tuberculosis in patient is formerly culture method which is time consuming and cumbersome. Various other techniques used in the diagnosis of tuberculosis have poor sensitivity and specificity however serum adenosine deaminase (ADA) has emerged as a potent biochemical marker that can be used as tool for the diagnosis of tuberculosis for rapid, easy and better result. Increased level of ADA in blood generally indicates the presence of tuberculosis. In the present study, the serum ADA level was examined in 75 healthy control and 75 tuberculosis patients with positive sputum smear for acid fast bacilli (AFB), having clinical symptoms were diagnosed for pulmonary tuberculosis and radiological impression for extra pulmonary tuberculosis. The selection of cases and control were based on the inclusion and exclusion criteria. Samples were collected at the outpatient department of National Tuberculosis Centre, Nepal after asking simple questionnaires. Modified Guisti and Galanti method was adopted for estimation of serum ADA from pooled and processed blood samples. There was significant difference (p<0.001) in mean rank of level of serum ADA among the TB cases to controls. The P-TB had the highest mean rank (116.52) followed by EP-TB (99.48) and control had significantly less mean rank (40.16). At the cut-off point of 25 U/L; sensitivity, specificity, positive predictive value and negative predictive value were 90.7%, 100%, 90.66% and 100% respectively. It can be concluded from data that there were insignificant difference in mean rank among sex wise distribution with p=0.037 and sputum grading wise distribution with p=0.142.

Cigarette smoking contribute to the development or progression of numerous chronic and age related disease processes. One major risk factor for morbidity and mortality among smokers is cardiovascular disease and lungs cancer. Hematological abnormalities have been associated with coronary heart disease and other oxidative damage at the tissue level increasing in age is significantly associated with higher hemoglobin concentration and C-reactive protein reactivity. The aim of the study was to find out the level of hemoglobin (Hb) and reactivity of C-reactive protein (CRP) among smoker and non-smoker. A comparative cross sectional community based study was conducted in Kathmandu valley (Swoyambhu, Thankot, Bhaktapur and Balkumari).Other medical records was taken into account and was analyzed. Hemoglobin level of smoker and non-smoker was estimated and it was compared with the qualitative test of CRP. A total of 150 healthy people (both smoker and non-smoker) aged 15-65 years were enrolled in this study for assessment of Hb and CRP. Blood hemoglobin was measured in 150 samples by Cyanmethemoglobin method and reactivity of CRP by latex turbidmetric method. Data were expressed in percentage, mean +SD. There was significant difference in mean value of hemoglobin level between smoker and non-smoker with P value 0.005.The difference in the reactivity of serum CRP among smoker and non-smoker was not significant enough with P value >0.05. The present study showed that the hemoglobin level of smoker group was higher than the non-smoker group as well as CRP showed reactive comparatively more in smoker than the non-smoker.

Background and Objective. Tibetan medicine is one of the earliest-known traditional medicines. This study aimed to evaluate the antioxidant, cytotoxic, and antibacterial potential of ethanolic extracts of nine common Tibetan formulations. Materials and Methods. An open-ended and semistructured questionnaire was used for an ethnomedicinal survey of the Tibetan formulations practiced in four Tibetan refugee settlements in Gandaki Province, Nepal. Based on the ethnomedicinal survey data, commonly used nine formulations were selected (Aru-18, Basam, Dadue, Dashel, Mutik-25, Raab Ga Yangzin Tea, Serdok-11, Sugmel-10, and Yungwa-4) to test biological activities. Antioxidant activity was evaluated using the 2,2-diphenyl-1-picryl-hydrazyl (DPPH) radical scavenging method. The cytotoxicity was examined by using the Allium cepa L. root tip meristem model. Similarly, the antibacterial effect was assessed by using well diffusion and broth dilution methods. Results. An ethnomedicinal survey showed a total of 52 Tibetan formulations were generally used by respondents for common diseases such as stomach disorders, diabetes, and migraine. From the antioxidant activity test, Sugmel-10 showed the highest DPPH free-radical-scavenging activity (IC50 1.8 μg/ml) and Yungwa-4 showed the lowest activity (IC50 5.2 μg/ml). Also, from the cytotoxic activity, the A. cepa root meristem model exhibited significant dose- and time-dependent growth suppression in Basam, Dadue, Mutik-25, and Serdok-11 as compared with cyclophosphamide standard drug. Similarly, Basam showed a good antibacterial effect having MIC 20 mg/ml and MBC 100 mg/ml against Enterococci faecalis. Conclusion. Research showed that Tibetan people preferred Tibetan formulations for the treatment and mitigation of several diseases. The result of antioxidant, cytotoxic, and antibacterial activities experimentally justified the ethnomedicinal value of nine common formulations (Aru-18, Basam, Dadue, Dashel, Mutik-25, Raab Ga Yangzin Tea, Serdok-11, Sugmel-10, and Yungwa-4). To the best of our knowledge, this study was performed for the first time in Nepal. Results from this preliminary study open the door to the scientific world to perform extensive pharmacological studies for designing and developing new therapeutic agents.
