Textile industry significantly contributes to the rapid economic growth rate of any countries. On the other sides, the textile industry uses a large amount of organic and inorganic chemicals as dyes that are directly or indirectly responsible for producing wastewater. The colored wastewater discharged from textile industries causes water pollution problems and it has been becoming one of the environmental concerns nowadays. The objective of this investigation was to explore the adsorption potential of rice husk (RH), as a low-cost adsorbent for the removal of Crystal Violet (CV) dye from textile wastewater. A single stage batch adsorber was designed to obtain the optimum condition for Crystal Violet (CV) dye removal. Equilibrium and kinetics studies were carried out to evaluate the adsorption of Crystal Violet (CV) onto rice husk. According to the equilibrium assessment, the adsorption data were best fitted with Freundlich isotherm. The adsorption kinetics followed the pseudo-second-order kinetic model. The results of this study indicate that rice husk is found to be a cost-effective and an efficient adsorbent for the removal of CV from textile wastewater.

Drug interactions between anti-tuberculosis and immunosuppressive medications after renal transplantation are a common problem in Myanmar. The efficacy of both types of drugs can be reduced during the treatment period, which can lead to graft failure and flare-ups of infection. Drug adjustments, with frequent monitoring and close follow-up, are crucial in this period. Ketoconazole decreases tacrolimus metabolism by inhibiting cytochrome P450-3A5 enzymes and P-glycoprotein. It is cost effective and has been frequently used to reduce the dose and cost of tacrolimus. Here, we report the case of a 56-year-old male renal transplant recipient with anti-tuberculosis medications.
