Abstract

Caffeine is a natural compund in many food and, such as coffee, tea, cocoa, and others. Indonesia is classified as one of the country which consume high number of caffeine. Eventhough caffeine can stimulate central nervous system, it may also bring undesireable effect such as infertility. Through this paper, we would like to review the effect of caffeine on females fertility and the safety limit of caffeine for daily consumption on women. This paper is made with study literature method. There are several studies which indicate that there is a strong relationship between caffeine consumption and infertility. The safety limit of the amount of caffeine that may affect fertility requires more research. Daily consumption of a cup of non-decaffeinated coffee of more showed a significant impact on fertility. There is greater risk of infertility at women who consume the greater amount of caffeine. Key words: caffeine, infertility

Abstract

Chocolate is one of the most common foods which many people consume. Chocolate has many effects to human health, one of which is for cardiovascular system. Some rumors say that chocolate has deteriorating effect for cardiovascular system because of its high fat content. On the other hand, the levels of antioxidants in chocolate said to have a positive effect on cardiovascular system. This paper discusses more about the cardiovascular effects of chocolate. Various literatures starting from year 2003 to 2008 related to the topic is collected to support the writing of this paper. From the results of this literature review, it was found that consumption of chocolate can provide short-term improvement on endothelial function and reduction in systolic and diastolic blood pressure. Other effects such as effects on fat profiles and pulse are still controversial. Underlying component of chocolate that contribute to these effects is flavanoid. Another component of chocolate feared to have deteriorating effect is stearic acid, that may increase blood cholesterol, but it is still not proven in various studies. Author concludes that chocolate has positive short-term effects for cardiovascular system. But because of the limitations of the various studies, long-term effects of chocolate consumption are still not known with certainty. Type of chocolate that was considered as the most useful for cardiovascular system is high-flavanoid content dark chocolate. Key words: chocolate, cardiovascular system, flavanoids, endothelial function, blood pressure

Abstract

Background The prevalence of type 2 diabetes mellitus (DM) is increasing. Diabetic patients have a higher risk of getting dermatomycosis. Dermatomycoses, although a common health problem amongst DM, is often misdiagnosed and consequently undertreated. Studies on the association between dermatomycosis and type 2 diabetes are lacking, especially in Indonesia. Therefore, the aim of this study was to determine the prevalence, etiology, and association of dermatomycosis with diabetic control of type 2 DM. MethodsA cross-sectional study was performed involving 87 subjects with type 2 DM. Demographic and clinical data, including age, sex, and blood glucose level, were collected. If a dermatomycosis lesion was found, a specimen would be taken for identification. Determination of serum glucose level was conducted using Roche c111 analyzer®. Statistical analysis was performed with the chi-square test and Kolmogorov-Smirnov two-independent sample test.ResultsSeventeen (19.55%) subjects had dermatomycosis. The predominant age group affected was 51 - 60 years (42.4%). The number of clinically apparent dermatomycosis was greater in the uncontrolled than in the controlled blood sugar group, but the difference was statistically not significant (p > 0.05). The lesions were mostly found on the nails (74%) and the most common etiology was candida (50%) followed by dermatophyte (25%) and non-dermatophyte molds (25%). ConclusionUncontrolled blood sugar tends to increase the risk of dermatomycosis in type 2 DM patients. Fungal skin infections are common in type-2 DM patients, especially in those with poor glycemic control.

Abstract

Background: A good collection of fungi culture can be maintained with good preservation methods. With appropriate methods, preservation can be performed in low-budget laboratories, such as with periodic subculture and preservation in either sterile water or in paraffin oil. The aim of this study was to assess the viability, morphology, contamination, and antifungal susceptibility profile of fungi preserved in sterile water or paraffin oil compared to a periodic subculture.Methods: This study was an experimental study using Aspergillus sp., Trichophyton mentagrophytes and Candida albicans. The fungi were preserved by a periodic subculture or in sterile water or in paraffin oil for six months. A comparison of viability, morphology, contamination, and antifungal susceptibility profile between methods were made before and after six months of study.Results: The viability of all the fungi was maintained in both periodic subculture and preservation with paraffin oil. However, the T. mentagrophytes was not viable in preservation using sterile water. All methods could maintain the morphology without contamination. There were reductions in the inhibition zone against antifungal drug in preservation with sterile water and paraffin oil.Conclusion: Preservation in paraffin oil is superior to preservation in sterile water in terms of maintaining fungal viability. This method is suitable for the use in a simple laboratory, albeit considerations should be given to the reduction of inhibition zone.

Abstract

Introduction: A good and proper preservation can maintain all collection of culture. Periodic subculture preservation is an old technique that is less able to guarantee the genetic characteristic for a long time. Sterile water is an alternative method in various studies to ensure the genetic characteristic for a long time and can be done in a simple laboratory concept. This study aimed to examine the method of periodic subculture and with sterile water Methods: This research was a descriptive study with an experimental laboratory design on Aspergillus sp. and Candida albicans. This study examined at periodic subculture methods and with sterile water in maintaining viability, level of contamination, morphology, and antifungal resistance after six months Results: The fungus had lived after being preserved with periodic subcultures without contamination, morphological changes, and resistance. Aspergillus sp. and Candida albicans also lived after being preserved with sterile water for six months with the same morphology and without contamination. The zone of inhibition of Aspergillus sp. had decreased but in Candida albicans remains the same. Conclusion: Preservation with periodic subculture and with sterile water can be applied to Aspergillus sp. and Candida albicans.
