BACKGROUND: The present study was undertaken to know health-related lifestyles of Republic of Korea Air Force (ROKAF) pilots and to investigate prevalence of obesity of them.METHODS: 1284 KAF pilots were checked their height, weight, and body composition (% body fat). We also tried questionnaires on their health-related lifestyles which included the effort to be healthy, whether they know weight training is beneficial to G-tolerance, exercise habit and smoking history. RESULTS: Pilots' attitude for health promotion was relatively passive. Many of them know that weight training is good for their G-tolerance, but only 8.1% of the pilots carried out that training. They engaged much more in aerobic training, and also fighter pilots are less participated in weight training than transport pilots. The prevalence of obesity (29.4%) determined by bioelectrical impedance analysis was much higher than that assessed on the basis of height and weight (BMI, body mass index). It is suggested that many pilots who were normal in BMI have abdominal or visceral obesity. CONCLUSION: The health promotion program and physical conditioning program related to increasing G tolerance of KAF pilots flying high-performance aircraft are very important. These programs must be organized and progressed with flight surgeon and Aeromedical center in Chung-ju as leaders.

Involucrin is a recently recognized structural component of mature squamous epithelial cells and is considered as a marker of normal eratinocyte differentiation and ma.turation. In this study peroxidase-antiperoxidase techniques were used to assess involucrin expression in histologic sections of normal skin and a variety of epidennal tumors including squamous cell carcinomas(25 cases), keratoacanthomas(11 cases), basal cell carcinomas(20 cases), trichoepitheliomas(5 cases), Howens diseases(12 cases), arsenic keratoses(10 cases), actinic keratoses(10 cases) and Pagets diseases(2 cases). The results were as follows : l. In normal skin, the upper third of the viable epidermis showed diffuse cytoplasmic staining for involucrin. In hair follicles, the lower area of inner root sheath and inner area of the outer root sheath stained positively. The sebareous glands did not stain, but the ducts of sebaceous glands were positive. 2. Keratoacanthomas showed a relatively homogeneous staining pattern for inirolucrin ', all cells except basal cells stained with mild to moderate intensity. In contrast, squamous cell carcinomas disclosed a highly irregular involucrin staining pattern with marked variation in staining intensity from cell to cell. 3. Basal cell carcinomas were negative for involucrin except squamous horn cysts, and the epidermis overlying basal cell carcinomas showed the field effect, that is, the epidermis overlying the tumors exhibited diffuse, homogeneous positive staining of cells in all layers of the epidermis. 4. ln trichoepitheliomas, the involucrin reactivity was negative as in basal cell carcinoma.s, but the field effect was not observed. 5. In Elowens disease, actinic keratosis, arsenic keratosis and Pagets disease, the positivit.y for involucrin staining extended deeper into the stratum malpighii than was observed wit,h normal epidermis. And areas showing irregular patchy pattern of involucrin staining were considered to have the potentiality of malignant invasive change much more than the negative or homogeneous areas. Paget's cells were negative for involucrin as the adjoining keratinocytes in the lower portion af epidermis.

It is difficult to know whether the presence of infection in the plantar ulcer in patients with leprosy or not. Because routine bacteriology is often unhelpful, we need to investigate diagnostic method in this situation. C-reactive protein(CRF) levels have been known to be useful in detecting infection in some diseases. In this study, CRP levels were measured in 20 leprosy patients with plantar ulceration and 14 patients with leprosy alone. The results were as follows : 1. There was no elevation of CRP levels in patients with leprosy alone, and in the majority of patients with ulcers. 2. Of 20 patients with plantar ulcers, four had raised CRP levels one had clinically obvious infection, and three had erythematous skin of uncertain cause surrounding their ulcers. 3. Treatment with an appropriate antibiotics reduced CRP levels to normal, which was associated with clinical improvement. Therefore, it is suggested that increased CRP levels can be a useful probe for detecting significant bacterial infection in plantar ulcers of leprosy patients.

OBJECTIVES: The purposes of this clinical study were 1) to assess 5-year survival rates in 195 patients with locally invasive cervical cancer(stage Ia-IIb) treated by surgery, neoadjuvant chemotherapy+surgery and postoperative radiation in selected cases, 2) to evaluate the prognostic factors affecting the survival rate, and 3) to get helpful information for the better treatment. METHODS: A retrospective analysis was conducted of 195 patients. They were diagnosed and operated on during the period of Jan. 1988 - Dec. 1993 in Dept. of OB/Gyn, Pusan Paik Hospital, Inje Medical School. The 5-year survival rates were estimated using the Kaplan-Meier method, and prognostic factors were assessed using Wilcoxon test. RESULTS: The 5-year survival rates for FIGO stages Ia, Ib, IIa, and IIb were 100, 86.1, 76.9, and 81.1%, respectively. Factors that affect the 5-year survival rates were clinical stage(P=0.0001), cell type(small cell vs other, P=0.0001), depth of invasion(< or = 5 mm vs >5 mm, P=0.0013), tumor size(< or = 3 cm vs >3cm, P=0.0035), and lymph node metastasis(0 vs 1 vs more than 2, P=0.0001). There was no difference in 5-year survival rates between without neoadjuvant chemotherapy group and with neoadjuvant chemotherapy group which had poor prognostic factors. The predicted recurrence rate of the postoperative radiation group showed a lower 5-year survival rate than the no postoperative radiation group(P=0.0001). CONCLUSIONS: We conclude that the factors affecting the prognosis were FIGO stage, cell type, depth of invasion, tumor size, and lymph node metastasis, and speculated that the survival rates could be improved by using neoadjuvant chemotherapy for more advanced locally invasive cases properly.

AIDS, which is being spreaded world-wide, would have the number of the patients and the infected persons to several million persons since the first patient had been reported among the homosexualists in 1981, and in our country patients of 323 persons had been found till 1993, therfore we could have significant concern and warning. Accordingly, this writer intended to present basic data to the blood Project and AIDS preventive movement by investigating knowledge, attitude and concern regarding AIDS including blood donors, and analyzed data of 1,920 pages by questionaire method from March to August 1994. According to the results, it is rather well-known as far as general knowledge, attitude and concern regarding AIDS are concerned, however, items which are 20-40% wrongly known are as followings: AIDS is infected by virus. It is infected by insects such as mosquito. It is infected with tight kiss with the person infected with AIDS. Risk of being infected with AIDS will be reduced if using condom when sexual intercourse. It may be infected through the foods. It may be infected by the same bacteria attacking venereal disease. And WHO(world Health Organization) designated Dec. 1st as AIDS'Day. Items which are 40-60 wrongly known are as followings: AIDS can be infected by blood donation, Now vaccine preventing AIDS has been developed. In our country, Preventive law of AIDS is established. And in the field of the attitude and concern, it was surveyed as important as being hahdied by the broadcasting and newspaper, and 60470% of the persons answered that they would avoid AIDS infected person, and 76% of male and 87.1% of female gave the reply thet AIDS infected persons should be administered extraordinarily by isolated accommodation by the nation.

Component fixation on the acetabular side is not as much of a problem because of the simpler geometry and loading configuration. It is generally accepted that hemispheric component design is preferable and immediate implant stability can be achieved by using screws or spikes in the porous coated implants. The authors reviewed 130 primary noncemented porouscoated, press fit acetabular component in 110 patients; 84 were AML (Anatomical Medullary Locking) and 46 were HarrisGalante acetabular component. Radiologic analysis at a minimum of 3 years(average 4.5 years) was done with special regards to the vertical and medial migration, screw size and numbers, change of the radiolucent line and its zone with its fate and acetabular cup angles on the acetabular component by the 2 observers. Progressive radiolucent line at the component-bone intersurface were found in 14 cases(11%), frequently located in zone I and zone I & II. No significant vertical, medial migration and change of the acetabular cup angle were found. No screw and spike failure had occurred. No component had to be revised because of loosening. As a whole, in our 3-years experience we report excellent results with porous coated acetabular component although it dose not ensure long-term sucess.

Tuberculous spondylitis is not rare disease. Today the posterior instrumentation and posterior or posterolateral fusion concomitant with the anterior decompression and anterior interbody fusion have been used for the treatment of spinal tuberculosis. The authors experienced a case of tuberculous spondylitis complicated with descending aortic pseudoaneurysm. An aneurysm is defined as a localized dilatation of an artery that is at least one-half the size greater than is expected for that artery. Pseudoaneurysm occurring after previous operation, trauma, and infection. Erosion of the thoracic aorta with the development of an fistula in the presence of infection is an unusual and difficult problem to manage. We report a case and review related articles briefly.

A non-adrenergic, non-cholinergic mechanism for the penile erection has been suggested after the observation that atropine or B-receptor antagonist fails to block penile erection produced by pelvic nerve stimulation. Vasoactive intestinal polypeptide(VIP) has merged as a strong candidate for a possible non-adrenergic, non-cholinergic inhibitory transmitter in penile erection. In this study, the effect of VIP and its relationship to adrenergic or cholinergic mechanism was observed using the isolated corpus cavernosal strip from the rabbit penis, and the action mechanism of VIP was investigated with special reference to release ot endothelium dependent relaxation factor (EDRF) and the mobilization of Ca++ and K+ ions. The corpus cavernosal strip was carefully prepared from rabbit penis and was suspended in an organ bath containing 1ml of Tyrode solution maintained at 37 degrees C. The Tyrode solution was aerated with 95% oxygen and 5% carbon dioxide. One end of the cavernosal strip was attached to the bottom of the bath and the other end to the force displacement transducer(FT. 03, Grass, Quincy, Mass.). When a stable tension level of the strip had been attained, drugs were added to the organ bath and the change of been attained, drugs were added to the organ bath and the change of motility of the strip was recorded on a Polygraph (Grass Model 7, Quincy, Mass.). The results obtained were as follows: 1. VIP caused a dose-dependent relaxation of the cavernosal strip of rabbit penis. 2. VIP pretreatment had no effect on the contraction induced by a1 and a2-adrenergic agonist. 3. VIP had no synergistic effect on the relaxation produced by acetylcholine or isoproterenol. 4. Neither atropine nor propranolol had any blocking effect on the VIP-induced relaxation. 5. Methylene blue decreased the relaxation of the cavernosal strip which was induced by VIP. 6. VIP had no effect on the contraction induced by either KCl 20mM or 80mM. 7. In calcium-free high potassium solution, VIP inhibited the calcium-induced contraction. From the above results, it is suggested that VIP exerts an endothelium dependent relaxing effect on the cavernosal strip of the rabbit penis via its own receptor which is associated, in part, with the inhibition of calcium influx.
