This study was undertaken to investigate mineral changes in weathered scalp hair after burial. EDX (energy dispersive X-ray spectroscopy) analysis was performed to measure the presence of minerals on the hair surface. Twelve scalp hairs, buried for 5-40 years, were chosen from deceased individuals buried in tombs in Soha-Ri, Kyonggi-Do, and other regions in Korea. Three normal hairs were used as the control group. EDX data showed that carbon, oxygen, and sulfur were detected in hair collected from all three burial grounds. In contrast, calcium was only detected in hair collected from tombs in Soha-ri. The amounts of calcium and sulfur were found to decrease with time for hair collected from tombs in Soha-ri. Similar results were observed with sodium for hair collected from other regions. These results show region specific mineral detection and a decrease in the concentration of minerals with time. Consequently, it is suggested that changes in minerals concentration in weathered hair could be used as basic data in the field of forensic medicine.

BACKGROUND: Although surgical angioplasty for isolated coronary ostial stenosis is assumend as an alternative approach to CABG, the clinical features of isolated coronary ostial stenosis, postoperative complications and follow-up angiographic results would have not been well studied. METHODS: We retrospectively studied 24 patients (female : male = 20 : 4, mean age 50.0 +/- 12.3 yr) who underwent surgical angioplasty for isolated coronary ostial stenosis using patch ( 22 fresh autologous pericardium, 2 saphenous vein) during the period of March 1990 through February 1998. Repeat coronary angiography (16 patients) and echocardiography (24 patients) were performed. Aortic regurgitation was evaluated semiquantitatively (Grade I - Grade IV). RESULTS: There were 3 deaths after surgical angioplasty. One death was due to acute coronary dissection perioperatively, the second due to low cardiac output syndrome 2 weeks post-surgery, and the third due to traumatic panperitonitis 10 months post-procedure. Angina recurred in 4 patients and the remaning 18 patients were symptom-free. Repeat angiography (19.3 +/- 20.7 Mo) showed widely patent ostium with excellent run-off except 2 patients (1 distal patch stenosis, 1 ostial restenosis in Takayasu's arteritis). The third symptomatic patient was proven to have coronary spasm by ergonovine test. AR increased in the fourth patient (Grade II -> III) with patent ostium. CONCLUSION: Surgical angioplasty may be feasible and alternative operative method to CABG for isolated coronary ostial stenosis. It should however be noted that postop AR can develop and/or increase. Further investigation is needed to evaluate the clinical significance of the AR.

OBJECTIVE: To overcome the limitations of the single gene transfer, the authors present the results of wild-type p16 and p53 combined genes transfer in vitro to the U251MG and U373MG cell lines using cationic liposome as a vector. METHODS: To compare the therapeutic effect of the combined p16 and p53 genes transfer with the single p16 and p53 gene transfer, full length of wild-type human p16 and p53 gene, and combined p16-p53 genes were transferred in vitro to the U251MG and U373MG cell lines using cationic liposome as a vector. As the U251MG and U373MG cell lines are devoid of p16 and p53 genes, the therapeutic effect of the three groups of gene transfer could be evaluated by the growth suppression or percentage of the viable cells. Reverse transcription polymerase chain reaction(RT-PCR), flow cytometry, and electron microscopy(EM) were used for evaluation of the growth suppression or apoptosis of the tumor cells. RESULTS: p16 gene, p53 gene and the combined p16-p53 genes were effectively transferred to the cell lines using cationic liposome as a vector resulting in dramatic decrease of the viable tumor cells in comparison to the control group(p=0.004). The cytotoxic effect of the gene transfer in the U251MG cell line was the most significant in the combined p16-p53 group. However, in the U373MG cell line p53 single gene transfer group showed more significant effect than the combined gene transfer group. Apoptosis was confirmed by EM in the combined p16-p53 genes group. The G1 phase arrest effect, confirmed by the flow cytometry was more prevalent in the p16 gene transfer group than the other groups. CONCLUSION: Cationic liposome-mediated transfer of combined p16-p53 genes to the human glioblastoma cell lines is proven effective. However, the therapeutic effect of the combined p16-p53 genes transfer was not consistently superior to the single p16 or p53 gene transfer.

OBJECTIVE: Pituitary apoplexy (PA) is described as a clinical syndrome characterized by sudden headache, vomiting, visual impairment, and meningismus caused by rapid enlargement of a pituitary adenoma. We retrospectively analyzed the clinical presentation and surgical outcome in PA presenting with cranial neuropathy. METHODS: Twelve cases (3.3%) of PA were retrospectively reviewed among 359 patients diagnosed with pituitary adenoma. The study included 6 males and 6 females. Mean age of patients was 49.0 years, with a range of 16 to 74 years. Follow-up duration ranged from 3 to 20 months, with an average of 12 months. All patients were submitted to surgery, using the transsphenoidal approach (TSA). RESULTS: Symptoms included abrupt headache (11/12), decreased visual acuity (12/12), visual field defect (11/12), and cranial nerve palsy of the third (5/12) and sixth (2/12). Mean height of the mass was 29.0 mm (range 15-46). Duration between the ictus and operation ranged from 1 to 15 days (mean 7.0). The symptom duration before operation and the recovery period of cranial neuropathy correlated significantly (p = 0.0286). TSA resulted in improvement of decreased visual acuity in 91.6%, visual field defect in 54.5%, and cranial neuropathy in 100% at 3 months after surgery. CONCLUSION: PA is a rare event, complicating 3.3% in our series. Even in blindness following pituitary apoplexy cases, improvement of cranial neuropathy is possible if adequate management is initiated in time. Surgical decompression must be considered as soon as possible in cases with severe visual impairment or cranial neuropathy.

Purpose: This study was undertaken to revise and update the Nutrition Quotient (NQ) for Korean adults, a tool used to evaluate dietary quality and behavior. Methods: The first 31 items of the measurable food behavior checklist were adopted based on considerations of the previous NQ checklist, recent literature reviews, national nutrition policies, and recommendations. A pilot survey was conducted on 100 adults aged 19 to 64 residing in Seoul and Gyeonggi Province from March to April 2021 using a provisional 26-item checklist. Pilot survey data were analyzed using factor analysis and frequency analysis to determine whether checklist items were well organized and responses to questions were well distributed, respectively. As a result, the number of items on the food behavior checklist was reduced to 23 for the nationwide survey, which was administered to 1,000 adults (470 men and 530 women) aged 19 to 64 from May to August 2021. The construct validity of the developed NQ (NQ-2021) was assessed using confirmatory factor analysis, linear structural relations. Results: Eighteen items in 3 categories, that is, balance (8 items), moderation (6 items), and practice (4 items), were finally included in NQ-2021 food behavior checklist. ‘Balance’ items addressed the intake frequencies of essential foods, ‘moderation’ items the frequencies of unhealthy food intakes or behaviors, and ‘practice’ items addressed eating behaviors. Items and categories were weighted using standardized path coefficients to calculate NQ-2021 scores. Conclusion The updated NQ-2021 appears to be suitable for easily and quickly assessing the diet qualities and behaviors of Korean adults.

In the case of crown-root fracture due to traumatic injury in anterior tooth and the fracture margin is located subgingivally,forced eruption has been proposed for the reconstruction of deficient bone and soft tissue. Forced eruption is one of the easiestorthodontic approaches that can have an acceptable outcome and prognosis, and has a low incidence of relapse. However, using heavy forces or very fast movements can also cause tissue damage or ankylosis. The following case reports present forced eruption as treatment option of crown fracture in maxillary anterior teeth.

Purpose: Acute sagittal injury in boxer’s knuckle causes extensor tendon subluxation. We analyzed anatomical measurements for posture-related hand parts and measured the force generated when striking the fingers. Methods: In 120 healthy adults (55 males, 65 females), the palm area, finger length, finger length, finger circumference, and wrist circumference were measured. Using a digital force gauge, the force generated by striking with finger flexion (FFF) performed by the middle finger was measured. The forces generated during extension flicking (FEFs) by the index and ring fingers were also measured. The forces exerted by the hand and fingers was measured using a grip force meter. The relationships of measured values with sex and age were statistically analyzed. Results: The FFF of the middle finger was 12.9±7.0 N, and the FEFs of the index and ring fingers were 6.8±2.5 N and 5.8±2.3 N, respectively. The grip force was 343.3±134.7 N in the four fingers excluding the thumb, 108.4±41.6 N in the index finger, 110.5±45.4 N in the middle finger, and 83.6±36.5 N in the ring finger. Males had higher FFF for the middle finger (17.9±6.6 N) than females (8.6±3.9 N) (p<0.001), and greater FEFs for the index (8.5±2.0 N) and ring fingers (7.1±2.2 N) compared to females (5.3±1.7 N and 4.7±.8 N, respectively) (p<0.001). Cross-analysis results showed differences by sex and age. The circumference of the index finger exceeded that of the ring finger. Conclusion The study findings shed light on the relationship between the forces generated in the process of finger flicking.
