The cytochrome P450 (CYP) 3A subfamily is estimated to participate in the biotransformation of 50% of the currently prescribed drugs. Four members of the CYP3A subfamily have been identified in humans: CYP3A4, CYP3A5, CYP3A7, and CYP3A43. Initial data suggested that CYP3A5 accounts for only a small proportion of the total hepatic CYP3A in about 20% of samples, but it was later revealed that CYP3A5 represents more than 50% of the total CYP3A amount in some individuals. Several genetic variants have been described for the CYP3A5 gene, of which the CYP3A5*3 allele (gA6986G), the most common form and leading to the loss of CYP3A5 activity, has been extensively investigated in the aspect of pharmacokinetics and disease risk. This review summarized the molecular characteristics of the CYP3A5 gene, and discusses the association of the CYP3A5*3 polymorphism with disease risks such as cancer and hypertension, along with its role in the pharmacokinetics of CYP3A substrates.

Intracranial vasculitis is a rare and disastrous complication of tuberculous meningitis if not treated properly. Focal neurologic deficits according to the vessels involved are common manifestation. Here, we report a 29-year-old man who suffered abrupt, bizarre behavioral changes caused by vasculitis complicating tuberculous meningoencephalitis. The diagnosis of tuberculous meningitis is based upon both the CSF findings and a chest X-ray. His systemic symptoms disappeared by after being administered antituberculous medication but various psychotic features such as hypersomnia, hyperphagia and aggressivebehavior continued. A brain MRI showed multiple small parenchymal tuberculous nodules, and the brain MR angiography revealed a narrowing of the proimal middle cerebral arteries and a reduced visualization of the cerebral vessels, suggesting widespread vasculitis. Intravenous dexamethasone successfully ameliorated his behavioral changes. In addition both the follow up brain MRI and angiography showed a normalization of the previous findings.

3.Mediating Effect of Self-Esteem on Relationship between Cultural Adaptation Stress and Achievement Motivation in Adolescents from Multicultural Families
Journal of Korean Academy of Psychiatric and Mental Health Nursing 2023;32(1):25-33
Purpose:
To understand mediating effects of self-esteem on the relation between acculturative stress and achievement motivation of adolescents from multicultural families.
Methods:
As a secondary analysis research using data of the 16th (2016) Youth Health Behavior Survey, this study selected a total of 1,239 middle school students from multicultural families. Using SPSS/WIN 24.0 Program, collected data were analyzed through descriptive statistics, t-test, one-way ANOVA, Scheffé’s test, Pearson’s correlation coefficients, Stepwise multiple regression, and SPSS Process Macro.
Results:
Achievement motivation had a significantly negative correlation with acculturative stress (r=-19, p<.001) while it had a positive correlation with self-esteem (r=.56, p<.001). Acculturative stress had a negative correlation with self-esteem (r=-23, p<.001). Self-esteem partially mediated the relation between acculturative stress and achievement motivation (95% CI, -0.05~-0.03).
Conclusion
Results of this study indirectly showed that the negative influence of acculturative stress on achievement motivation could be reduced through enhancement of self-esteem. Thus, to improve achievement motivation of adolescents from multicultural families, it would be necessary to develop and provide programs for enhancing self-esteem.

Ultrasound (US)-guided hydrodissection (HD) is a widely applied therapeutic method to release the entrapped peripheral nerve. However, this therapy has only been studied for the nerve entrapments such as carpal tunnel syndrome, and there are no reports of its effect on direct nerve injuries with incomplete axonal damage. Here, we report a case of direct traumatic injury of a median nerve with incomplete axonal injury in a 28-year-old man. He presented hypoesthesia and weakness along with the median nerve territory of the left hand after a laceration wound of the wrist. The patient underwent a surgical procedure, but did not experience prominent improvement for the next six months. Symptoms improved after we performed the US-guided HD with dextrose. We propose this procedure as one of the new treatment methods for direct axonal injury of nerves including the median nerve.

PURPOSE: To evaluate the usefulness of CT features of appendiceal mucocele in the diagnosis and evaluation of complications. MATERIALS AND METHODS: We retrospectively reviewed CT findings and compared with operative findings in 7 cases of pathologically proven appendiceal mucocele. CT findings such as location and extent of the lesion, Issue density, thickness or calcification of the wall, presence of adjacent inflammatory infiltration, and visualization of normal vermiform appendix were analyzed. RESULTS: Appendiceal mucocele was found as homogeneous low density cystic mass adjacent to the cecum, which has no surrounding inflammatory infiltration except in one case of perforation and one case of intussusception. Mean CT number measured in 4 cases was 21 Hounsfield unit. Thin curvilinear calcifications were noted along the cystic wall in 2 cases. Normal vermiform appendix couldn't be demonstrated in all cases. CONCLUSION: Appendiceal mucocele is characterized by homogeneously low density and thin walled cystic tumor adjacent to cecum without surrounding inflammatory infiltration, and absence of normal vermiform appendix on CT. Therefore, CT is valuable in preventing operative complications of appendiceal mucocele.

PURPOSE:Recent studies proposed that polyunsaturated fatty acids (PUFA) of the omega6 series (linoleic acid, LA) compared to the omega 3 series (linolenic acid, LNA) may be a potent promoters of adipogenesis during the gestation/lactation period. Increased ratio of LA/LNA may stimulate adipose tissue development during gestation/lactation period and may subsequently lead to chilhood obesity. The purpose of this study is to evaluate fatty acids composition of the breast milk in Korean lactating women and to analyze the relationship between LA/LNA and the body weight gain of the infants. METHODS:Fifty eight healthy postpartum lactating women and their healthy 58 breast feeding infants were studied. At 11.3+/-3.9 days of postpartum, breast milk were taken and analyzed by gas-liquid chromatography with one-step methylation method. RESULTS:The total fat contents in breast milk were 3.2+/-1.3%. The total fat contents in breast milk were not related to maternal BMI or Kaup index of infants. The percentage of PUFA was 24.9+/-6.0%. Among these PUFA, the percentage of LA and LNA was 20.3+/-5.8% and 2.2+/-0.8%, respectively. LA/ LNA ratio was 10.2+/-2.5. There were no significant correlations between LA/LNA ratio and infant weight gain during the first 2 months of life. CONCLUSION: Short term weight gain of infant was not related to the LA/LNA ratio in the breast milk. Further studies on the long term effects on fat percent and body weight of infants would be needed.

Genes of cancer-associated testis antigens (CTAs) are expressed in various cancer tissues. In order to use CTAs as cancer diagnosis marker, we developed molecular method for detection of CTAs transcripts in tissue. In order to know the applicability of DNA of cancer-associated testis antigens (CTAs) on cancer diagnosis, molecular diagnostic methods for detection of gene expression of melanoma antigen gene (MAGE), GAGE, and B melanoma antigen (BAGE) was studied. After comparing DNA sequences of CTAs, S1/AS1 and S2/AS2, GAGE-S/ GAGE-AS, and BAGE-S/BAGE-AS primers were designed for the detection of MAGEs, GAGEs and BAGEs, respectively. The gene expression of CTAs in cancer cell lines, head and neck cancer tissues, ovary cancer tissue, and peritoneal cells of gastric cancer patients were investigated by reverse transcription-polymerase chain reaction (RT-PCR) using these primers. The MAGEs, GAGEs and BAGE genes were expressed in 8/8 (100%), 5/8 (62.5%) and 1/8 (12.5%) of head and neck cancer tissues, respectively. The gene expression of MAGEs were also detected in 8/10 (80%) of ovary cancer tissues and in 9/10 (90%) of peritoneal cells of gastric cancer patients in RT-PCR test using S1/AS1 primers. The results of this study suggest that molecular diagnosis method using CTAs genes, especially RT-PCR using S1/AS1 primer combination, is useful for diagnosis of cancer and it will be used for the prediction of cancer progression or regression and metastasis in future.
