PRELIMINARY STUDY REGARDING THE FORMULATION AND PHYSICAL EVALUATION OF SOME BIOCOMPATIBLE, OIL IN WATER MICROEMULSIONS WITH SALICYLIC ACID FOR DERMATOLOGIC USE

ABSTRAK Tanaman daun Jambu mete adalah salah satu tanaman yang mengandung senyawa flavonoid yang dapat berperan sebagai antioksidan yaitu mampu menangkap radikal bebas pada kulit. Hand and Body lotion adalah suatu sediaan yang dibuat dari bahan dasar dengan penambahan ekstrak daun jambu mete, serta penambahan bahan lain yang diizinkan dan digunakan untuk kulit. Jenis penelitian yang digunakan adalah eksperimen. Sediaan hand and body lotion dengan 3 konsentrasi yaitu konsentrasi 2%, konsentrasi 3%, dan konsentrasi 5% dan dilakukan pengujian evaluasi fisik yaitu uji organoleptik, pH, tipe emulsi, stabilitas emulsi, homogenitas, viskositas dan iritasi. Hasil penelitian menunjukkan bahwa ekstrak daun jambu mete dapat diformulasi dalam kosmetik hand and body lotion. Hasil penelitian menunjukan uji organoleptik diperoleh sediaan semi padat yang berwarna coklat muda dan memiliki aroma khas green tea yang dapat tercampur dengan air dengan tipe emulsi minyak dalam air (M/A) , dan stabil yaitu tidak terpisahkan antara fase air dan fase minyak selama penyimpanan. Kata Kunci : Hand and Body Lotion, daun Jambu Mete, antioksidan. ABSTRACT Flavonoid is compound that contain from jambu mete leaves have a role as the antioxidant like a foid from free radikal skin. Hand and body lotion is a preparations that mad from basic lotion material with add pollen jambu mete leaves and other metrial which necessary and use for skin. This research that made in a pollen is eksperiment. Hand and body lotion with three concentration 2%, concentration 3%, concentration 5% and do a physical evaluation test are organoleptic, pH, type of emulsion stability, homogeneity, viscosity, and irritation. The result show that a pollen from Jambu Mete leaves can be formulated in cosmetic hand and body lotion. This resultshow that organoleptik test got semi oreparation which is colored light brown and have aroma typical green tea that can mixed with water emulcion type oil in water (0/W) and stable is not separate between water phase and oil phase until storage. Keywords : hand and body lotion Jambu Mete leaves, antioxidant.

Ammonia Oxidizing Bacterium

This research is a preliminary study conducted to determine the effects of aspirin (acetyl-salicylic acid) and salicylic acid (analgesics and their derivatives) on the antibiotic resistance of ammonia oxidizing bacterium (AOB) (a non-pathogenic environmental microbe) cultured from the Texas Tech University—Water Recovery System that treats a space related wastewater for NASA. The effect of salicylic acid was investigated by obtaining the minimal inhibition concentration (MIC) of antibiotics (amoxicillin, ciprofloxacin, and nalidixic acid) in the presence of aspirin and salicylic acid. The possibility of transfer of resistance genes between unrelated species was investigated by analyzing the similarity of the AcrA protein (a multi-drug efflux protein) in Nitrosomonaseuropaea, Escherichia coli and Salmonella enterica. The protein alignment analysis was done using ExPASy, a proteomics tool. The results of this preliminary study indicated that the antibiotic resistance of AOBs increased in the presence of aspirin and salicylic acid and similarities in the AcrA protein of different species indicated the likelihood of possible resistance transfer between the species. This paper high lights the importance of research and further investigation on antibiotic resistance and resistance transfer, highlighting the number of parameters that should be considered while assessing antibiotic resistance in environmental samples.

Hormonal Therapies

A preliminary study of human mammary carcinoma on the ultrastructural level is reported for a metastatic, subcutaneous nodule, obtained as a surgical biopsy. The patient's tumor had responded favorably to a series of hormonal therapies, including androgens, estrogens, progestins, and corticoids for recurring nodules over eight years. The pertinent nodule was removed from the region of the gluteal maximus, two weeks following stilbestrol therapy. It was about 1.5 cms in diameter, and was located within the dermis. Pieces from it were fixed immediately in cold fixatives: phosphate buffered osmium tetroxide, glutaraldehyde, and paraformaldehyde. Embedment in each case was in Vestopal W. Contrasting was done with combinations of uranyl acetate and lead hydroxide.

Preliminary Study

A new strain of mice, which had arisen by mutation from a dystrophic mouse colony was designated ‘mdx’, because the genetic defect, which manifests itself in brief periods of muscle destruction followed by episodes of muscle regeneration appears to be X-linked. Further studies of histopathological changes in muscle from ‘mdx’ mice at the light microscopic or electron microscopic levels have been published, but only one preliminary study has been on the tibialis anterior (TA) of ‘mdx’ mice less than four weeks old. Lesions in the ‘mdx’ mice vary between different muscles, and centronucleation of fibers in all muscles studied so far appears to be especially prominent in older mice. Lesions in young ‘mdx’ mice have not been studied extensively, and the results appear to be at variance with one another. The degenerative and regenerative aspects of the lesions in the TA of 23 to 26-day-old ‘mdx’ mice appear to vary quantitatively.

Preliminary Study

Left ventricular assist systems are being developed for eventual long term or permanent implantation as an alternative to heart transplantation in patients unsuitable for or denied the transplant option. Evaluation of the effects of these devices upon normal physiology is required. A preliminary study was conducted to evaluate the morphology of aortic tissue from calves implanted with a pneumatic Left Ventricular Assist device-LVAD. Two 3 month old heifer calves (calf 1 and calf 2) were electively explanted after 128 days and 47 days respectively. Descending thoracic aortic tissue from both animals was removed immediately post mortem and placed into karnovsky’s fixative. The tissue was subsequently processed for transmission electron microscopy (TEM). Some aortic tissue was fixed in neutral buffered formalin and processed for routine light microscopy.
