A new simple, accurate and low cost-effective UV-VIS spectrophotometric methods has been developed for the analysis of chosen cephalosporins (ceftriaxone, ceftazidime) in bulk samples and pharmaceutical dosage forms by using a specific color-generated reaction. This method involves the Schiff 's base formation reaction between selected cephalosporins with alcoholic 5-sulfo salicylaldehyde reagent 5SSA with heating to establish a yellow colored product displaying λmax at 426 nm as well as 412 nm sequentially. These methods applied to the Beer’s law through the range of concentration was …
A third-generation cephalosporin antibiotic was aceftriaxone medicine. Similar another (3rd generation cephalosporins), it has wide broad spectrum effectiveness versus gram positive as well as gram negative bacteria. Diverse approachs for analyses of the studied medicine are obtainable but are costly additionally time consumption. Therefor we have sophisticated developed novel, easy, simple as well as accurate colormetric approach for investigation of ceftriaxone medicine as pure form as well as in formulation vials by depending on a specific color-generated reaction. This reaction involves …

Rice is a principal food source for most of the world's population. Rice has many nutrients including thiamin hydrocloride (THC) and pyrodoxine hydrocloride (PHC). Before consumption, rice is usually processed such as milling, washing, and cooking. Determination of THC on IR-64 and Rojolele rice with washing three times has been conducted. Also determined of PHC on the milled IR-64 rice and the pounded IR-64 rice. The THC was determined by spectrophotometric method at 246 nm. Determination of PHC based on the coupling reaction with diazo reagent in alkaline solution to form azo dye then the ab…
Meloxicam (MLX) is a nonsteroidal anti-inflammatory drugs (NSAID) which belong to Biopharmaceutical Classification System (BCS) class II, which have a low solubility level with a high permeability. Therefore, to enchance is solubility level, physical modification of the meloxicam is required. It can be done by the cocrystal formation. Cocrystal contained active ingredients and coformer which bind through the hydrogen bond. This study used malonic acid (MA), since it contained carboxylic group which expected to form hydrogen bonds. Slurry is a method of cocrystal formation by mixing two ingre…

Anthropogenic forest fires, including those occurring in the pine forests of Thailand, have been widely reported. Although pine forests are fire dependent, too frequent burning could be unhealthy for the forest as it might result in nutrient depletion and ecosystem degradation. Hence, this study aimed to examine the effects of forest fire on the vegetation structure and composition of a degraded pine forest (PF) and in a mixed pine-oak forest (O-PF) of Phu Kum Khao, Nam Nao National Park, Phetchabun Province, Thailand. The effects of fire in one year were studied using three 50 x 50 m experime…
Streptomyces sp 45I-3 producing xylanase was isolated from Kalimantan soil sample. Crude enzyme (produced by centrifuging the culture at 14000 rpm for about 5 minutes) and purified xylanase has an optimum condition at pH 5 and 50 oC. Crude xylanase have half-life time of 2 hours 9 minute at 50 oC, whereas purified xylanase has half-life time of 12 hours. The molecular mass of purified xylanase was determined to be 43.2 and 39.2 kDa.
High environmental temperatures may cause heat stress in poultry. This may increase water consumption, decrease feed consumption and in rum, decrease productivity level. In addition, high temperature contributes to oxidative stress, a condition where oxidant activity (free radicals) exceeds antioxidant activity. In our research, antanan (Centelta asiatica) and vitamin C were utilized as anti heat-stress agents for heat-stressed broilers. We used 120 male broilers 2 - 6 weeks old, kept at 31.98 ± 1.94 °C during the day and 27.36 ± 1.31 °C at night. The data collected wer…
