This study attempted to analyze trends of structural changes in the front middle part of men's underwear and get basic data for the development of men's underwear patterns. In terms of a research method, the structure and pattern of the front middle part of men's underwear were analyzed by referring to the design and description of the drawing, focusing on men's underwear which targeted to isolate penis from scrotum among the 'men's underwear' or 'functional men's underwear'-related patents. According to the study, three topics were obtained as follows: a support attached to the inside of the front middle part; inner cloth attached to the inside of the front middle part; change in the structure of the front middle panel. The aspects by the specific topic targeted to isolate penis from scrotum and prevent the scrotum from adhered to a thigh are as follows: 1) When a support is attached to the inside of the front middle part, the following three methods are proposed: Penis isolated from scrotum by a rest which is designed using the band; penis and scrotum rested in the band and in a pocket respectively; protruded rest inside the front middle part of the underwear. 2) When an inner cloth is attached to the inside of the front middle part, the following methods are designed: A pocket-type inner cloth is attached; isolation of penis hole from the scrotum pocket using a rectangular separator; U-shaped pocket designed to rest penis and scrotum is attached. 3) Regarding change in the structure of the front middle panel, the integration of penis and scrotum resting parts can be divided into two cases: Securing a space using wrinkles; keeping it voluminous using the vertical line. In this all-in-one penis and scrotum-holding type, in addition, different front panel patterns were applied.

Purpose: Lymphedema of the scrotum and penis is a functionally and emotionally incapacitating problem for patients. Patients suffer pain from swelling, chronic irritation, repeated infections, drainage, and sexual dysfunction. Although there are various methods for the treatment of scrotal and penial lymphedema, achieving a satisfactory reconstruction in severe cases still remains a challenge due to the lack of locally available tissue. Methods: A 33-year-old man sustained severe lymphedema of the scrotum and penis. He reported a history of swelling since 25 years, which had been intensified during the past few months. There was no history of irritation, surgery, trauma, infection or travel to endemic countries. The authors reconstructed the scrotum and penis using 4 scrotal flaps made by incising the enlarged scrotum crucially. Results: The postoperative course was uneventful. Histopathologic examination showed nonspecific chronic inflammation. The patient was followed up for 18 months and a good reconstructive result was obtained with no recurrence. Conclusion: The authors' method is safe and easy to perform. This method may be a convenient and reliable alternative for the treatment of severe lymphedema of the scrotum and penis.

Purpose: By virtue of good nourishment, obese boys are increasing in Korea, which may result in prevalence of cryptopenis. As milieu of economy, culture, and society changes, increased attention to the external genitalia in children should encourage surgeon to do assertive treatment for cryptopenis. But various operative methods have been devised yet to need sophistication and revision. The author performed suprapubic lipectomy and operation according to the modification of the Johnston's principle. Methods: The patient was 5 years old, 32 kg, and 122 cm. He had no pain or tenderness. The operation was done under general anesthesia. It was done with excision of suprapubic fat, cutting of retracted dartos fascia instead of removing the fascia around penile base, and anchoring of dermis and the cutting margin of the fascia to the underlying fascia such as Buck's fascia, tunica albuginea and rectus fascia at penile base. And then circumcision was performed. Results: Postoperative complication was not observed. The clinical result of the operation was satisfactory to both surgeon and parents of the patient. Conclusion: Suprapubic lipectomy and anchoring of dermis and retracted cutting dartos fascia margin to the underlying fascia in all directions at the penile base through a single suprapubic incision provide this patient with complacency.

Children above age of two are able to have sexual excitement, and they actively seek the pleasure actively or passively through touch and masturbation. In late $60_s$ and early $70_s$, Masters, obstetrician, and Johnson, social worker, illustrated four phases of human sexual responses, namely excitement, plateau, orgasmic and resolution phases in both sexes, and multiple orgasms in the female. Their treatment principles of sexual dysfunctions were largely based on behavioral model, introducing the concepts of sensate focus, dual therapy and sex education. Following Masters and Johnson, Kaplan, psychiatrist and psychoanalyst, in the early and mid-$70_s$ introduced new sex therapy which was based on the combination of analytically-oriented psychotherapy and behavior therapy, and classified sexual dysfunctions into three categories such as desire excitement and orgasmic phase disorders. Since $1980_s$ other medical fields joined the stream, putting the concentrated effort on the treatment of the impotence in the male. They have developed penile prosthesis, local injection therapy, and the administration of oral medications. Nowadays Sildenafil(Viagra) seems the best choice for the treatment of the impotence in the male.

Objectives : Assuming that the characteristic of meridian system has been similar to this of electric potentials in human body and that measurements of electric potential at well(井穴) and sea(合穴) points in branches of the twelves meridians will be representative of measurements of the twelve meridians, to measure the electric potentials in twenty healthy volunteers when they were sleeping or waking respectively, to do significance test for electric potential of meridian system between hand and foot meridian, yin and yang meridian, exterior and interior of the body, and among the five elements. Methods : When twenty healthy volunteers were sleeping, their electric potentials of well and sea points in branches of the twelve meridians were simultaneously measured by physiograph. After a minute we measured them again, totally 5 times. And then when they were waking, their electric potentials were measured 5 times by the above method. Results : Measurements were analyzed by statistical t-test, we obtained that the left side electric potential of hand or yin meridian was significantly different from that of foot or yang meridian both sleeping and waking. The right side of electric potential was the same result as the left side's. Most of the t-test was significant between exterior and interior of the body, and among the five elements. That meaned that it was partly possible to apply the ancient theory of meridians to the study of electric potential at well and sea points in branches of the twelves meridians.

The role of nitric oxide (NO) on the non-adrenergic non-cholinergic (NANC) relaxations induced by the short and prolonged electrical field stimulation (EFS) has been studied in the rabbit corpus cavernosum. In the presence of atropine and guanethidine the prolonged EFS (2-16 Hz) of corpus cavernosal strips precontracted with phenylephrine produced frequency-dependent relaxations, which were abolished by tetrodotoxin as shown in the relaxations induced gy the short EFS, indicating that their orgin is NANC nerve stimulation. $N^G$-nitro-L-arginine (L-NNA), inhibitor of nitirc oxide synthase, caused a concentration-dependent inhibition to the NANC relaxation, and at 100 M L-NNA the relaxation were virtually abolished. The inhibitory effect of L-NNA was reversed by L-arginine. Hemoglobin abolished the relaxations to NO and also caused a concentration-dependent inhibition of the NANC relaxation. The hemoglobin-resistant relaxation induced by EFS was eliminated by L-NNA. Methylene blue significantly reduced the NANC relaxation in a conentration-dependent manner. The NANC relaxation was not affected by a VIP-inactivating pepridase, alpha0chymotrypsin, whereas VIP-induced relaxation was completely abolished. NO- and VIP-induced relaxation were not affected by L-NNA. These results indicate that the NANC relaxation induced by prolonged EFS of the rabbit corpus cavernosum is mediated by NO-guanosine 3',5'-cyclic monophosphate pathway as shown in the relaxation induced by the short EFS, and that VIP release is not essential for the NANC relaxation of the rabbit corpus cavernosum and VIP is not involved the generation fo NO.

Objectives : These present study was designed to investigate the relaxation effects of Alpiniae Oxyphyllae Fructus(AOF) on isolated corpus cavernosum smooth muscle.Methods : Rabbit corpus cavernous tissues were prepared in strip. Then relaxation responses of AOF at 0.01-3 ㎎/㎖ in contracted strips induced by phenylephrine(PE) were measured. To evaluate mechanisms, indomethacin(IM) tetraethylammonium chloride(TEA), Nω-nitro-L-arginine(_L-NNA), methylene blue(MB) were treated before AOF extract(0.1-3 ㎎/㎖) infused into precontracted strips induced by PE. And 1 mM Ca²⁺was infused into precontracted strips after pretreatment of AOF extract(3 ㎎/㎖) in Ca²⁺-free krebs-ringer solution. NO concentration was measured by Griess reagent system. Ratio of smooth muscles to collagen fibers and eNOS positive reaction were measured by histocheminal and immunohistochemical process.Results : The cavernous strips were significantly relaxed by AOF extract 0.1, 0.3, 1, 3 ㎎/㎖ and the pretreatment with IM 10 μM,_L-NNA 100 μM, MB 10 μM inhibited relaxation of AOF compared to non-pretreatment, but the pretreatment with TEA 100 μM didn't affect relaxation of AOF. In a Ca²⁺-free solution, pretreatment with AOF reduced increase on contraction of strips by Ca²⁺supply than non-pretreatment. On HUVEC, NO concentration was increased. On corpus cavernosum of penis in Spontaneous Hypertensive Rat, ratio of smooth muscles to collagen fibers and eNOS positive reaction in AOF group were increased compared to PE groupConclusions : Taken this results, we can suggest that AOF extract exerts a relaxation effects on rabbit corpus cavernosum smooth muscle in part by suppressing influx of extracellular Ca²⁺throughout prostacyclin, the NO-cGMP system.

As a part of estimating quantitative radiation treatment doses, we produced a mathematical phantom based on the standard Korean male. Then, with the prostate as the source organ, we calculated the absorbed dose in the prostate and surrounding organs forecasted to occur during brachytherapy for prostate cancer. To simulate the procedure, we selected $^{25}I$ and $^{103}Pd$ useful in brachytherapy of the prostate as the radionucleids and made an assumption that 1 Ci of initial radioactivity is administered. As a result, we found that the prostate, as the source organ, indicated 101 Gy/Ci and 7.24 Gy/Ci, respectively, in case of $^{125}I$ and $^{103}Pd$. With the exception of the prostate, organs with high absorbed doses were found to be in the order of the penis and scrotum, sigmoid colon, testicles and the urinary bladder, which are relatively close to the prostate.

A total of 31 human diphyllobothriasis cases have been reported in Korea. Authors experienced two more human cases of Diphyllobothrium latum infection, especially due to eating raw freshwater trout. Two cases were husband and wife in a famil residing in Chunchon city, Kangwon-do, who raw fish in October 1994. A 43-year old male(husband) was 69kg in body weight and healthy. A worm (6.65m in length; 8-l3mm in width) was expelled from him after, anthelmintic treatment. The second case(wife) was a 39-year old female who weighted 56kg. She complained about gastrointestinal trouble and abdominal discomfort. A worm (5.50m in length; 9-l3mm in width) was Obtained her after anthelmintic treatment. No scolex was collected from the two worms. Two patients were administrated with praziquantel(15mg/kg of body weight) and 15gm of magnesium sulfate as a purgative. Two worms identified as D. latum, .based on the following biological characters: extermal morphologies, coiling of uterus, the number of uterine loops, position of genital opening, morphologies of cirrus and cirrus sac and seminal vesicle on the histological sections, positions of vagina and uterine pore, distribution patterns of vitellaria, and microscopical and SEM morphologies of the egg.

This study aimed to investigate the relaxation effects and its underlying mechanisms of Epimedium koreanum Nakai(EK) in phenylephrine(PE) treated isolated rabbit corpus cavernosum smooth muscle. The dose-dependent relaxation responses of phenylephrine(PE, $1{\times}10^{-6}M$)-precontracted strips to EK at $0.01-3.0mg/m{\ell}$ were measured and also observed after endothelial denudation using organ bath. To analyze the underlying mechanisms of EK-induced relaxation, $N{\omega}$-nitro-L-arginine(L-NNA), methylene blue(MB), tetraethylammonium chloride(TEA), indomethacin(IM) were pretreated before EK extract infused into precontracted strips induced by PE. To investigate cytotoxic activity and nitric oxide(NO) concentration of EK extract on EA.hy926 cells, mitochondrial dehydrogenase activity(MTT) assay and nitric oxide detection kit were used. The cavernous strips were significantly relaxed by EK extract at $0.3mg/m{\ell}$, $1.0mg/m{\ell}$, $3.0mg/m{\ell}$ and the relaxation responses of PE-precontracted strips denuded endothelium also inhibited in comparison with intact endothelium. The pretreatment of L-NNA, MB, TEA reduced EK extract-induced endothelium-dependent relaxation, but the pretreatment of IM didn't affect EK extract-induced endothelium-dependent relaxation. When EK extract was applicated on EA.hy926 cells, the NO concentration was increased. Our findings have shown that EK extract exerts a relaxing effect on corpus cavernosum in part by suppressing influx of extracellular $Ca^{2+}$ through activating the NO-cGMP system.
