AIM: This study aims to determine the effect of hydrolysed virgin coconut oil (HVCO) to increase cell proliferation, COX-2 expression of NIH 3T3. METHODS: The sample used was Virgin Coconut Oil (VCO). VCO was partially hydrolysed using lipase from Rhizomucor miehei (active on sn-1,3 position) to produce hydrolysed VCO (HVCO) composed of free fatty acids, 2-monoglycerides. Then acid value was determined. The effect of HVCO on proliferation was evaluated using the MTT method. Wound healing assay was established by a cell migration method, and COX-2 expression was determined using RT-PCR. RESULTS: Acid value is 135.89 ± 0.12 mg NaOH/g oil and free fatty acids (FFA) is 48.50 ± 0.06%. The effect of HVCO 62.5 µg/mL on cell proliferation after 24h, 48h, and 72h incubation found as viable cells are 109.24 ± 0.52%; 118.26 ± 0.91% and 106.59 ± 0.74%. Percent of wound closed after 24 h and 48 h incubation are 69.94 ± 0.54% and 100.00 ± 0.00%, and expression of COX-2 increased from 1 (control) to 1.83 (HVCO). CONCLUSION: The results suggest that HVCO is effective to increase cells proliferation and hence wound healing process.

The first line drug given for monotherapy for diabetes mellitus type 2 is metformin hydrochloride, which is a biguanide antihyperglycemic drug. The aim of this research was to develop, validate, and apply the Fourier Transform Infrared spectrophotometry method to identify and determine metformin hydrochloride in marketed tablet dosage form. This research included preparation of standard, analysis of samples, and validation of method. The specific wavenumber obtained for qualitative analysis was 1645.68 cm–1 and 1574.8 cm–1. The specific area obtained for quantitative analysis with a single baseline ranged from 1701.53 cm–1 to 1535.66 cm–1. All metformin hydrochloride marketed tablet dosage forms were analyzed and met all of the qualitative and quantitative requirements. The methods met the requirements of method validation for accuracy with a percentage of recovery of 100.22 %, precision with relative standard deviation of 0.48 %, linearity with a correlation coefficient of 0.9992, limit of detection of 11.17 mg per mL, limit of quantitation of 33.84 mg per mL, and good specificity results. In this study, the Fourier Transform Infrared spectrophotometry method was successfully developed and validated for application in identification and determination of metformin hydrochloride in marketed tablet dosage form.

Senggani plants also have a reddish purple flower, ripe fruit will break the color purple and reddish brown beans. However, the utilization of senggani leaves is still not getting attention, therefore, to increase the economic value and utilization of this plant, senggani leaf can be formulated in the extract ointment of senggani leaf ethanol to healing the cut on the rabbit so it is expected to give healing effect on the rabbit wound.The purpose of this research is to know the concentration of ethanol extract of senggani leaf in the formulation of the ointment which is most effective in healing the rabbit wound in rabbit and to know the ointment ratio of ethanol extract of senggani leaves with betadine ointment .The samples in this study were extract from senggani leaf extracted by maceration using 80% ethanol solvent and formulated in ointment preparation using ingredients of adeps lanae and vaseline album. All data were tested statistically using ANOVA ONE WAY.Preparation of ointment extract of ethanol senggani leaf can accelerate the healing process of the wound and the most effective is the syrup leaf extract of 50% with an average healing for 11 days while betadine ointment does not experience healing until day 14.Indicating differences between treatment groups were more effective in healing of cuts on rabbits and 50% extracts of ethanol extracts of senggani leaf were more effective than with betadine ointment.

AIM: The objective of the study was to evaluate protein expression in NIH 3T3 cells that are treated with virgin coconut oil (VCO) and hydrolysed of virgin coconut oil (HVCO) in vitro. METHODS: Coconut oil used in this study was virgin coconut oil (VCO) and VCO hydrolysed by Rhizomucor miehei (HVCO). NIH 3T3 cells (5x105 cells/well) were seeded in nine wells and incubated for overnight, then divided into three groups. Each group consisted of three wells. Group one without treatment, group two added VCO, and group three added HVCO and then incubated for overnight. One well in each group was added MMP-9, PDGF-BB, and TGF-β1 and incubated one hour. Finally, expressions of MMP-9, PDGF-BB, and TGF-β1 were detected using immunocytochemistry method. RESULTS: The results of the study showed that VCO and HVCO increased protein expressions of MMP-9, PDGF-BB, and TGF-β1. Percentage of MMP-9 expressions treated by VCO increased from 2.89 ± 0.07 to 28.16 ± 0.34, PDGF-BB from 28.11 ± 0.13 to 48.53 ± 0.49, and TGF-β1 from 4.19 ± 0.08 to 18.41 ± 0.54. Percentage of MMP-9 expressions treated by HVCO increased from 2.89 ± 0.07 to 55.40 ± 0.94, PDGF-BB from 28.11 ± 0.13 to 61.65 ± 0.42, and TGF-β1 from 4.19 ± 0.08 to 36.35 ± 0.67. CONCLUSION: VCO and HVCO increase the expression of MMP-9, PDGF-BB, dan TGF-β1 in NIH3T3 cells and therefore, coconut oil active in the wound healing process. HVCO is more than active than VCO.

Tea is a drink that is very familiar in the world and is very common in everyday life. Tea is also the most consumed and favored beverage by the public after water. Besides being beneficial, tea also contains compounds that have a negative impact on the body, namely caffeine compounds. Caffeine is an alkaloid of the methylxanthine group which plays a role in increasing the work of psychomotor in the body, and side effects that can be caused are anxiety, irregular heartbeat, difficulty sleeping, tremors, diuresis and others. The purpose of this study was to determine the caffeine content in black tea powder circulating in the Old Deli market. This type of research is descriptive with a purposive sampling method. The analytical method used is qualitative with murexide and quantitative ultraviolet spectrophotometry with a wavelength of 267nm. The results of a qualitative analysis of all positive samples contained caffeine. The average quantitative yield of caffeine in brand A black tea powder was (4,82 ±0,0356)%, B brand black tea powder (4,89 ± 0,0173)% and C brand black tea powder (4,93 ± 0,0531)%. The validation test results obtained linearity r = 0,9984, LOD and LOQ is 0,8074 mcg/ml and 2,6914 mcg/ml ,% recovery = 100,07%, RSD = 0,33%. Based on the results of research conducted, it can be concluded that ultraviolet spectrophotometry can be used to determine caffeine levels in black tea powder.
