    Evisceration of umbilical content with extensive adhesion: A surgical approach
    Mishra, P ; Yadav, VK ; Hasan, M (WILEY, 2020-12)
    With timely recognition and surgical intervention along with administration of an antibiotic, antihistaminic, and anti-inflammatory drugs, evisceration of umbilical content with extensive adhesion can be treated, and the outcome is also good.

    OBJECTIVE: This study was undertaken to compare the curative efficacy of marigold leaf paste and turmeric paste on healing the incised wound in sheep. The study also determined the antimicrobial effects and histopathological changes in a wound's healing process treated with these medicinal herbs. MATERIALS AND METHODS: Surgical wounds (n = 18) were created aseptically in the skin of the flank region of six healthy sheep dividing them into three experimental groups. Follow-up data were taken up to day 21. Different morphological characteristics of the wound and wound contraction (length and width) were recorded weekly. Samples were collected on days 1, 2, and 3 to test the antimicrobial effects and on days 1, 3, and 7 for histopathological studies. RESULTS: Treatment with marigold leaf paste and turmeric paste resulted in a swelled wound area of 11.78 ± 0.38 mm and 11.52 ± 0.27 mm, respectively. The wound areas were comparatively lower than that of the control group (11.44 ± 0.20 mm). Moreover, the least elevation (2.44 ± 0.12 mm) of the sutured line from the skin surface was noted and compared between the marigold leaf paste and normal saline (2.74 ± 0.13 mm). Bacterial colonies in the nutrient agar medium cultured with swabs from the normal saline-treated group's wound area were found on day 1. On the contrary, bacterial colonies were absent on days 2 and 3 of treatment in the groups treated with both the paste of marigold leaves and turmeric. Less intense tissue reactions and higher keratinization of epithelium were shown in the group treated with marigold leaf paste than turmeric paste and saline-treated groups. CONCLUSION: Marigold leaf paste showed less tissue reaction and healed the wounds effectively. Thus, this paste could be used for the treatment of superficial wounds in sheep.

    Prediction of Epidemics Trend of COVID-19 in Bangladesh
    Hassan, R ; Dosar, AS ; Mondol, JK ; Khan, TH ; Al Noman, A ; Sayem, MS ; Hasan, M ; Juyena, NS (FRONTIERS MEDIA SA, 2020-11-30)
    Background: Amid a critical and emergent situation like the coronavirus disease (COVID-19) pandemic related to extreme health and economic repercussions, we used and presented the mathematical modeling like susceptible-infectious-recovered (SIR) to have a numerical demonstration that can shed light to decide the fate of the scourge in Bangladesh. To describe the idea about the factors influencing the outbreak data, we presented the current situation of the COVID-19 outbreak with graphical trends. Methods: Primary data were collected and analyzed by using a pre-created Google Survey form having a pre-set questionnaire on the social distancing status of different districts. Secondary data on the total and the daily number of laboratory tests, confirmed positive cases, and death cases were extracted from the publicly available sources to make predictions. We estimated the basic reproduction number (R◦) based on the SIR mathematical model and predicted the probable fate of this pandemic in Bangladesh. Results: Quarantine situations in different regions of Bangladesh were evaluated and presented. We also provided tentative forecasts until 31 May 2020 and found that the predicted curve followed the actual curve approximately. Estimated R◦-values (6.924) indicated that infection rate would be greater than the recovery rate. Furthermore, by calibrating the parameters of the SIR model to fit the reported data, we assume the ultimate ending of the pandemic in Bangladesh by December 2022. Conclusion: We hope that the results of our analysis could contribute to the elucidation of critical aspects of this outbreak and help the concerned authority toward decision making.

    Standard feeding strategies with natural insemination improved fertility in repeat breeding dairy cows
    Hasan, MMI ; Hasan, M ; Harun-Or-Rashid, M ; Rahman, M ; Rahman, MS ; Juyena, NS (NETWORK VETERINARIANS BANGLADESH, 2021-06)
    OBJECTIVE: The experiment was designed to establish suitable management strategies through the different feeding and breeding approaches on fertility improvement in the experimental repeat breeding (RB) cows. MATERIALS AND METHODS: 80 RB cows were selected for this experiment. Before grouping, all cows were deworming and then divided into four equal groups, namely Group-TF1 [traditional feeding practice and natural insemination (NI)], Group-TF2 [traditional feeding practice and Artificial insemination (AI)], Group-SF1 [standard (STD) feeding practice and NI], and Group-SF2 (STD feeding practice and AI). These allocated RB cows were fed by traditional and STD feeding methods for 90 days and then inseminated by AI and NI breeding systems. The dominant follicle (DF) diameter, hemato-biochemical elements, and estrogen (E2) hormone were estimated during the insemination of cows. Estimation of the pregnancy rate was carried out at days 45-90 post-insemination in the cows. RESULTS: The pregnancy rate was significantly (p < 0.05) higher in STD feeding practice with NI when compared to traditional feeding practice irrespective of breeding systems, and it was also significantly (p < 0.05) higher in NI than in AI breeding system, irrespective of feeding strategies. The results also showed that the diameter of DF, serum E2, total erythrocyte count, hemoglobin, packed cell volume, total cholesterol, total protein, glucose, calcium, phosphorus, ferric iron, copper, zinc, and magnesium at the time of insemination were significantly (p < 0.01) elevated in the experimental RB cows with STD feeding practice. The diameter of DF and serum E2 were significant (p < 0.01) and positively correlated with all hemato-biochemical elements in the cows at the time of insemination. CONCLUSION: The results suggest that NI with STD feeding practice may increase fertility in RB cows by improving general health status. Finally, it could support the veterinarians and researchers to define the management strategies using feeding and breeding strategies to prevent repeat breeding syndrome in dairy cows.
