1.Studies on the metabolism of C(14)-proline in some parasitic helminths.
The Korean Journal of Parasitology 1964;2(3):159-164
A comparison of the absorption and incorporation of C(14)-proline into protein by the 7 kinds of helminth parasites is presented. The radioactivity of free amino acid fraction is greater than that of protein fraction in all the worms, and only a small amount of exogenous labeled proline is incorporated into tissue protein. In general, the pattern of C(14)-proline uptake and its incorporation into protein shows rapid linear increase during the period of 15 to 30 min and reaches the maximum at 60 min after incubation, and then the equilibrium state was maintained throughout further incubation.

Ketamine is a safe and effective drug for pediatric anesthesia, sedation and analgesia. We hoped to identify that surgeons could operate a pediatric hernia with the ketamine anesthesia without general anesthesia. The study was a consecutive case series of 2230 inguinal hernia patients aged 1 months to 17 years in a Joo's day-surgical clinic during 11-year period. The patients had pediatric inguinal hernia surgery without general anesthesia under the day-surgery system. We retrospectively analyzed the medical record of patients who were registered with the Diagnosis Related Group (DRG) system. All patients received ketamine (5mg/kg) and atropine (0.01mg/kg) intramuscularly before surgery. After anesthesia, we injected 1~2% lidocaine (Less than 5ml) subcutaneously at the site of incision and started operation. The surgical method was the high ligation method of the hernia sac.) In total 2230 patients, male were 1756 and female were 474. 2076 patients were a unilateral inguinal hernia at the time of surgery and 154 were bilateral hernia patients. Less than three months, depending on the age of the patients was 391, and less than 12 months the patient was 592 people (26.5%). After surgery, there were no accidents or long term complications associated with ketamine anesthesia. We think the surgeon can safely do the pediatric inguinal hernia surgery using ketamine and lidocaine without anesthesiologist through 11 years of our surgical experiences.

3.The Effect of Uremic Plasma on the Proliferative Activity of CFU-GM in in-vitro Culture of Mouse Bone Marrow.
Korean Journal of Pathology 1987;21(4):215-226
The increased susceptibility in patients of chronic renal failure to infection has been reported to be attributed to defects in granulocyte and lymphocyte function and proliferative activity of hematopoietic cells. The definite cause of the frequent infection in uremic patients, however, is still controversial. The effect of uremic plasma on the aspect of the hematopoietic cells has been scarcely been studied. In the present study, mouse bone marrow was cultured with uremic plasma, to evaluate the effect of uremic plasma on the proliferative activity and morphological features of CFU-GM. The results obtained were as follows. 1) The number of colonies in group co-cultured with uremic plasma was more reduced than that of normal plasma group. 2) There was no difference between the group cultured with predialytic uremic plasma and that of postdialytic plasma in number of colonies, macroclusters and microclusters. 3) The forms of colony were granulocytic and monocytic forms at 5 day of culture. Electron microscopically, granulocytes disclosed electron dense azurophilic granules and electrolucent specific granules in the cytoplasm, and monocyte showed numerous vesicles and vacuoles in the cytoplasm which had finger-like projections. 4) The molecular weight of inhibitory factor in the uremic plasma was supposed to be less than 50,000 daltons.

4.A Case of Weber-Cockayne Epidermolysis Bullosa Simplex - Ultrastructural Findings.
Korean Journal of Dermatology 1997;35(1):214-219
Epidermolysis bullosa simplex (EBS) is a group of autosomal dominantly inherited genetic disorders characterized by blistering due to mechanical- stress-induced degeneration of basal epiderrnal cells. Recently, it was discovered that EBS is induced by keratin 5 and 14 gene mutations. Weber Cockayne (W-C) EBS is the mildest type, with blistering concentrates primarily on palar and plantar regions, and basal cell cytolysis by keratin filament perturbations is present. Herein we report a case of W-C EBS with its ultrastructural findings. Electron microscopy showed cytolysis and separation of the basal epidermal cells, mainly at the subnuclear cytoplasm. The cyto- plasm of basal cells showed edema, loosening and intact rnitochondria. Besides the cytoplasmic changes, the nucleus also showed lytic degeneration. Characteristically, dense condensation of tonofilarnent was observed, which suggests that W-C EBS is. also a disorder of keratin.

8.A clinical and pathological study of Becker's nevus.
Korean Journal of Dermatology 1993;31(4):539-547
BACKGROUND: Beckers nevus is a benign lesion that may be congental or acquired, macular or papular, hairless or hypertrichotie. OBJECTIVE: Our pcrpose was to describe the clinical findings of Eeckers nevus and to establish a method for the histologic diagnosis of Beckers nevus. MEHTODS: We reviewed PF skin biopsies and their clinical finding from 28 patients with Beckers nevus during a 10 year period from January 1981 to January 1991. Results : The results were summarized as follows. A Clinical characteristics 1. Sex distribution showed of male predominence with male female a ratio of 1.5:1. Age of onset was predominent in less that 5 years old and puberty. 2. The lesions were located on the trunk(24 cases), head & neck(8 cases), extremities(6 cases), and were repsilateral in 26 cases, bilateral in 2 cases. 3. The lesions were accompanied by hair in 17 cases(61%). The shaies of the lesions were reticulated (75 %), patch(18%), mottled(7%). 4. Hairs were distributed as follows : abdomen(100%), scapula(100 %), extremities (83%), cheek(80 %), neck(67 %), chest(40%). All lesions of the face had follicular papules. 5. Associated skin diseases were : smooth muscle hamartoma(3 cases), striae distensa(2 cases), steroid acne(2 cases), pigmented nevus(2 cases), and verruca plana(1 case). B. Histopathologic characteristics 1. The lesions were accompanied with plugs in 21 cases, which were follicular, acrosyringeal, epidermal. 2. Elongation of the rete ridge and hyperpigmented basal cells were observed in the epidermis in all cases. 3. The shape of the rete ridge in Beckers nevus has its characteristic appearance, which is single, bridging and reticulated. Single, bridging and reticulated shapes cexisted in 17 cases(61%). 4. Inflammatiry cell infiltrations were present in all of the upper drmis, in which melanophages(21 %), hair follicles(89%) and smooth muscle hamartoma(3cases) w ere observed CONCLUSION: These findings indicated that the shape of the rete ridge in Beckers nevus has its characteristic appesrance and can be useful for the diagnosis of Beckers nevus.

9.Antidepressant and the Quality of Life of Depressive Patient.
Journal of the Korean Society of Biological Psychiatry 1997;4(1):116-120
This study investigated the antidepressant efficacy and it's impact on the quality of life of depressed patients. We performed Hamilton Depression Rating Scale(HDRS), and Montgomery-Asberg Depression Rating Scale(MADRS), and Health-related Quality of Life Questionnaire(HQLQ) to both tricyclic antidepressant(TCA) and sertraline groups. There were 16 subjects in the study. The tricyclic group had 9 subjects and the sertraline group had 7. The TCA and sertraline produced a similar degree of response. Both groups experienced a reduction of 70% or more in mean HDRS and MADRS total score after 6wks. In HQLQ, the TCAs group also showed improved bed disability days, alertness behavior, and social interaction, the sertraline group showed improved health perception, alertness behavior, home management, and social interaction. We suggested that the improvement of "Quality of life" were not in proportion to the clinical symptom's improvement. Therefore, clinicians should consider the benefit of antidepressant treatment in terms of quality of life.

10.Pharmacogenomics of Depressive Disorders.
Journal of the Korean Society of Biological Psychiatry 2001;8(2):226-232
The phamacotherapy of depression has reduced morbidity and improved outcome for many depressive patients. A wide range of classical and new antidepressants are available for their treatment. However, 30-40% of all patients do not respond sufficiently to the initial treatment and present adverse effects. Pharmacogenetics studies the genetic basis of an individual's ability to respond to pharmacotherapy. Recently, some reports on serotonin transporter gene polymorphisms and their influence on the response to antidepressive therapy provide an interesting diagnostic tool in assessing the chances of response to antidepressants. We also investigated the relationship between serotonin transprter polymorphisms(5-HTTLPR) and the long-term effect of the antidepressant treatment. 128 depressive patients were enrolled into 2nd year study. The therapeutic response of each subset was not different at 8th, 16th week. but the subset with homozygote(l/l) of long variant showed a better therapeutic response to antidepressant than the heterozygote(l/s) of long and short variant, which showed a better therapeutic response than the subset with homozygote(s/s) of short variant at 1st year and 2nd year after the antidepressant treatment. This result shows that the serotonin transporter polymorphisms may be related to the long-term effect of antidepressant treatment. The potential for pharmacogenomics. the use of genetic increasing attention pharmacogenomics will contribute to individualize drug choice by using genotype to predict positive clinical outcomes, adverse reactions, and levels of drug metabolism. Personalized medicine the use of marker-assisted diagnosis and targeted therapies derived from an individual molecular profile, will impact the antidepressant therapy and this approach will replace the traditional trial-and-error practice of medicine.
