Background: Postoperative pain management following minimally invasive repair of pectus excavatum (MIRPE) remains a critical concern due to severe post-procedural pain. Promising results have been reported for cryoanalgesia following MIRPE; however, its invasiveness, single-lung ventilation, and additional instrumentation requirements remain obstacles. Serratus anterior plane block (SAPB) is a regional block technique capable of covering the anterior chest wall at the T2-9 levels, which are affected by MIRPE. We hypothesized that SAPB would be a superior alternative pain control modality that reduces postoperative pain more effectively than conventional methods. Methods: We conducted a retrospective study of patients who underwent MIRPE between March 2022 and August 2023. The efficacy of pain control was compared between group N (conventional pain management, n=24) and group S (SAPB, n=26). Group N received intravenous patient-controlled analgesia (IV-PCA) and subcutaneous local anesthetic infusion. Group S received bilateral continuous SAPB with 0.3% ropivacaine after a bilateral bolus injection of 30 mL of 0.25% ropivacaine with baseline IV-PCA. Pain levels were evaluated using a Visual Analog Scale (VAS) at 1, 3, 6, 12, 24, 48, and 72 hours postoperatively and total intravenous rescue analgesic consumption by morphine milligram equivalents (MME). Results: Mean VAS scores were significantly lower in group S than in group N throughout the 72-hour postoperative period (p<0.01). Group S showed significantly lower MME at postoperative 72 hours (group N: 108.53, group S: 16.61; p<0.01). Conclusion: SAPB improved immediate postoperative pain control in both the resting and dynamic states and reduced opioid consumption compared to conventional management.

본 연구에서는 관동맥 혈류가 감소된 부위에 혈중 방사성의약품의 농도를 증가시킴으로서 심근내 섭취를 향상 시킬 수 있을 것이라는 가정 하에 관동맥조영술 시에 관동맥 내에 Tl-201를 직접 주사한 후 SPECT 영상을 얻어 심근 분절의 섭취 정도를 평가하였다. 이 심근영상을 생존심근의 진단에 이용되는 아데노신 부하-재주사 TI-201 SPECT 영상의 심근 내 방사성의약품의 섭취 정도와 비교하였다. 대상 및 방법: 심장 초음파검사에서 심벽운동의 이상이 있고, 관동맥조영술을 시행할 예정인 14명의 관동맥질환자를 대상으로 연구를 시행하였다. 남자가 11명이었고, 평균연령은 54세(36-73세)였다. 관동맥내 주사 TI-201 SPECT 영상은 관동맥조영술을 시행한 환자들을 대상으로 관동맥조영술이 끝나기 직전에 TI-201 111 MBq(3 mCi)를 나누어서 각각 좌, 우관동맥 내에 각각 직접 주사하여 얻었다. 아데노신 부하-재주사 TI-201 SPECT 영상은 TI-201 2-3mCi를 정맥주사 후 아데노신 부하영상을 얻고 4시간 후에 TI-201 1mCi를 재주사한 후 다시 영상을 얻었다. 심근분절의 섭취정도에 따라 0-3의 4등급으로 분류하였다. 정상적인 섭취를 등급 0, 경도로 감소된 섭취를 등급 1, 중등도로 감소된 섭취를 등급 2, 심하게 감소되었거나 관류결손이 나타난 분절은 등급 3으로 분류하였다. 생존된 심근의 판정은 부하영상 재주사후의 영상, 또는 관동맥주사후의 영상 모두에서 심근 분절의 섭취정도가 등급 0, 1인 경우는 생존심근으로 판정하였고, 심근 분절의 Tl-201 섭취가 정상분절 섭취의 50%이하이며 역치를 50%로 설정 한 color coding으로 black-out하였을 때, 결손으로 나타나는 등급 2, 3을 비생존 심근으로 판단하였다. 결과 총 14명의 환자 중 14%에 해당하는 2명의 관동맥내 주사 영상은 낮은 계수율로 인하여 심장의 경계가 정확하게 구분되지 않거나 분절을 명확하게 구분할 수 없을 정도로 영상이 깨끗하지 못하였으므로 본 연구의 심근분절 섭취 분석에서 제외하였고 나머지 12명의 영상에서 총 252분절을 구분하여 섭취 정도를 분석하였다. 관동맥내 주사 영상에서 0등급-1등급이었던 192개의 분절을 생존심근으로 판단하였고, 재주사 영상에서는 0등급-1등급이었던 214개의 분절이 각각 생존심근으로 나타났다. 두 영상에서의 관류등급 평가에 대한 일치율은 76.5%였으며 생존능 평가에 대한 일치율은 90.5%였다. 부하-재주사영상시 비생존심근으로 나타난 38개의 분절 중 단 1개의 분절만이 관동맥내 주사 영상에서 생존심근인 것으로 판단할 소견을 보였으며, 부하-재주사 영상에서 생존심근인 것으로 나타났던 214개의 분절 중에서는 23개의 분절은 관동맥주사 영상시 오히려 생존능이 없는 것으로 하향 평가 되었다. 결론: Tl-201 관동맥내 주사 SPECT 영상은 Tl-201 부하-재주사 SPECT 영상과 비교하였을 때, 심근의 생존능을 평가하는데 있어 어느 정도 도움을 줄 수는 있으나 우월하지 않았다. 관동맥내 주사 영상은 6시간에서 24시간이 지나 얻은 지연영상의 낮은 계수율 때문으로 좋지 않은 결과를 얻었을 것 이 라 판단되었고, 조기에 영상을 얻기가 어려운 현실에서, Tl-201 관동맥내 주사 영상의 임상적 유용성은 제한적일 것이다.

The purpose of this study was attempted to investigate the number changes of the growing and mature follicles in ovary following repeats of pregnant mare serum gonadotropin(PMSG) treatments for superovulation in nulliparous rats. Thirty two rats(Sprague-Dawely, about 200~250 gm) were randomized into 4 groups. Control group rats were sacrified at estrus phase confirmed by vaginal smear. PMSG-treated group 1 rats, PMSG-treated group 2 rats and PMSG-treated group 3 rats were sacrified at 48 hrs after injection once with PMSG 25 IU, after 2 repeated injection by a week interval, and 3 repeated injection, respectively. The uteri and ovaries of rats were removed and weighed and then were observed grossly and serial sections of all ovaries and some sections of uteri by paraffin embedding were stained with H-E. Number of ovarian follicles about 3 grades of small, middle and large follicles from seondary and follicles were investigated by LM photographies of ovary preparations. The criteria of the small, middle, and large follicles were based as small follicle with preantral follicles with 2~4 layers of granulosa cells surrounding the oocyte, as secondary follicles with more than 5 layers of granulosa cells and early signs of antral cavity or with small clefts on either side of the oocytes, and as tirtiary follicles with a single medium sized antral cavity or large well-formed antral cavity, respectively. In gross findings, the wall of the uteri in control group were thin, and those in 3 PMS-treated group were markedly thickened and some uterine lumen of those filled with fluid. In histological findings, the walls of the uteri from 3 PMSG-treated groups were hypertrophied and their blood and lymph vessels were dilated than those of control group. The ovaries fo 3 PMSG-treated groups were more increased in size and the cortexes were more developed and increased in width but there are no difference of development and changes in 3 PMSG-treated groups. The weight of the uteri and ovaries per rat in PMSG -treated group 1, 2 and 3 were a, pp.ared to be significantly increased 171.4$\pm$47.6%, 162.3$\pm$43.9%, 206.9$\pm$30.4%, respectively than those of control groups. The mean number of follicle per ovary in control group were a, pp.ared to be 17.1$\pm$3.5, 46.2$\pm$14.5, and 74.3$\pm$22.7 at large, middle and small follicles, respectively and total number of these 3 grade follicles per ovary were a, pp.ared to be 137.7$\pm$31.7. The mean number of follicle per ovary in PMSG-treated group 1 were a, pp.ared to be 25.6$\pm$7.3, 78.1$\pm$29.9, and 83.2$\pm$34.0, at large, middle and small follicles, respectively and total number of these 3 grade follicles were a, pp.ared to be 187.5$\pm$58.8. The mean number of follicle per ovary in PMS-treated group 2 were a, pp.ared to be 21.9$\pm$5.2, 67.8$\pm$16.8, and 68.0$\pm$14.9 at large, middle and small follicles, respectively and total number of these 3 grade follicles were a, pp.ared to be 157.7$\pm$26.2. The mean number of follicle per ovary in PMS-treated group 3 were a, pp.ared to be 21.7$\pm$4.8, 61.5$\pm$17.0, and 59.7$\pm$16.2 at large, middle and small follicles, respectively and total number of these 3 grade follicles were a, pp.ared to be 143.5$\pm$29.6. The number of follicles in PMSG-treated group 1 a, pp.ared to be more number than other 2 PMSG-treated gruops and tended to be decreased by frequency of PMSG-treatment.

크립토스포리디움은 염소내성이 매우 강해 일반적인 표준정수처리공정의 소독으로는 제거가 불가능하다. 따라서 본 연구에서는 오존 및 UV를 이용한 단위소독공정에서 DAPI/PI 및 in vitro excystation을 이용하여 크립토스포리디움 불활성화를 평가하였으며, 또한 오존을 이용한 고도산화처리 파일럿에서는 세포배양법을 이용하여 크립토스포리디움 불활성화를 평가하였다. 오존 소독연구는 50 mL 용량의 piston type batch reactor에서 용존오존을 자동적으로 측정해주는 flow injection analysis (FIA) 시스템을 이용하여 실험한 결과, 1 log 제거에 필요한 CT값은 $25^{\circ}C$에서 DAPI/PI 및 in vitro excystation에 의해 각각 약 1.8, 2.2 $mg/L{\cdot}min$으로 나타났으며, 2 log 제거에 필요한 CT값은 각각 약 3.2, 3.8 $mg/L{\cdot}min$으로 나타났다. 또한 $5^{\circ}C$에서 크립토스포리디움 1 log 제거에 필요한 CT값은 DAPI/PI 방법에 의해 약 9.1 $mg/L{\cdot}min$으로 나타났으며, 2 log제거에 필요한 CT값은 14.8 $mg/L{\cdot}min$로 나타나, 같은 소독효과를 나타내기 위해서 저온에서는 상온에서보다 요존 요구량이 약 $4{\sim}5$배 정도 증가하여야 함을 확인하였다. 40 L규모의 오존 반응조를 이용한 파일럿 실험에서는 정수처리공정상 모래여과를 거친 물에 살아있는 크립토스포리디움을 접종한 것을 시료로 하여 연속적으로 흐르게 한 다음, 오존량을 변화시키고 체류시간은 5분으로 고정하여 불활성화를 평가하였다. 실험결과, 8 $mg/L{\cdot}min$의 CT값에서 DAPI/PI 및 excystation과 같은 생사판별법을 이용하였을 경우에는 약 0.2 log정도의 불활성화를 나타내었으며, 세포감염시험법을 이용하였을 경우에는 약 1.2 log정도의 불활성화를 나타냈다. 오존에 의한 크립토스포리디움의 소독능 평가에 단위공정 및 파일럿 실험 모두 2가지 생사판별법(DAPI/PI와 excystation) 사이에는 큰 차이를 나타내지 않았으나, 생사판별법과 세포감염시험법 사이에는 현저한 차이를 나타내었는데, 이는 세포감염시험법으로 측정하는 sporozoite 및 merozoite로의 분화과정이 생사판별법이 근거한 세포벽의 구조와 기능 유지 보다 더 오존 소독에 더 민감함을 알 수 있었다. 파일럿 실험에서의 CT값이 piston batch reactor에서의 CT값 보다 낮게 나타난 것은 파일럿 실험에서 수작업으로 인한 용존 오존 측정이 정밀하지 못하여 IOD가 농도에 반영되지 않았고, 반응조 규모(50 mL vs 40 L) 및 형태(회분식 vs 연속식)의 차이에 기인하는 것으로 여겨진다. 한편, UV를 이용한 단위공정에서는 크립토스포리디움 1, 2 log 제거에 필요한 IT값은 $25^{\circ}C$에서 각각 DAPI/PI 방법에 의해 약 25, 50 $mWs/cm^2$로 나타났으며, $5^{\circ}C$에서의 크립토스포리디움 1, 2 log제거에 필요한 IT값은 약 40, 80 $mWs/cm^2$로 나타났다. 온도 $20^{\circ}C$ 감소 시 약 60% 정도의 IT값이 더 필요한데, 이것은 저온에서는 약한 자외선을 발산하는 저압저출력 UV 램프의 특성 때문인 것으로 사료되었다.

카르복시테라피(Carboxytherapy)는 메조테라피(mesotherapy)와 방법, 치료 조건 및 결과 면에서 매우 유사하다. 그러나 중요한 차이점은 카르복시테라피는 이산화탄소 가스를 피부 바로 아래의 피하층으로 주입하는 반면 메조테라피는 비타민, 미네랄, 그리고 약물의 혼합물을 주입한다는 것이다. 메조테라피의 합병증으로 혈종, 파누스육아종, 봉와직염, 농양 등 이전에 많은 사례들이 보고되었으나, 카르복시테라피는 피하 및 얕은층에 이산화탄소를 주입하고, 이산화탄소는 주입 1주일 안에 흡수되기 때문에 부작용이 거의 보고 되지 않았다. 3일전과 2주전에 한의원에서 카르복시테라피를 받은 29세 여자 환자가 고열, 근육통, 심한 요통 및 엉덩이 부위부터 아래쪽 흉벽까지 피하 기종을 주소로 응급실에 내원하였다. 진단 및 치료를 위해 컴퓨터 단층 촬영을 시행하였으며, 즉시 영상의학과에 판단을 의뢰하였다. 바늘에 의한 손상으로 인한 급성 복막염을 배제할 수 없어 즉각적인 광범위항생제를 투여하였으며, 판독 결과 근육염과 바늘 손상으로 인한 신우신염이 확진되었다. 신우 신염의 경우 적절한 치료가 이루어지지 않으면 패혈증까지 진행할 수 있어 치명적인 결과를 초래 할 수 있다. 따라서 만일 바늘에 찔리거나 침을 맞은 후에 환자가 늑골척추부위나 허리에 통증이 있는 경우 응급의학과 의사는 진단 및 치료를 위해 신속한 초기 평가가 필요하다.

This study was performed to evaluate the effect of topical and intravenous heparin on thrombosis and patency in the microvascular anastomosis of the traumatized veins. Nine white rabbits weighing about 2 kg were used. After exposure of both femoral veins, the veins were crushed by the jaws of smooth needle holder in order to create a thrombosis model. Transectional incision was made in the vein. The animals were then divided into 3 groups based on the administration method of heparin: 1) Experimental Group I, topical irrigation of lumen with heparin saline solution (n=6); 2) Experimental Group 2, topical irrigation of lumen with heparin saline solution and intravenous injection of heparin (0.75 mg/kg) via the marginal ear vein for 3 days; 3) Control Group, topical irrigation of lumen with saline solution (n=6). The patency was evaluated with empty-and-refill test and thrombus formation was judged by surgical microscope. The results were as follows: 1. Thirty minutes after microvascular anastomosis, the patency of all Experimental Groups was better than Control group. However, there was no significant difference among groups. 2. Three days after anastomosis, the patency of all Experimental Groups was much more improved than that of Control Group (P<0.05). There was no significant difference between Experimental Group 1 and 2. 3. Three days after anastomosis, the amount of thrombus in all Experimental Groups was much less than that of Control Group (P<0.05). 4. In histologic findings a lot of luminal thrombus were observed around sutured area in Control Groups. Few luminal thrombus was observed in all Experimental Groups. Mild necrosis in the vessel wall was observed around sutured area in all specimens. These results indicate that topical irrigation of heparin may improve the patency and inhibit the formation thrombus in the microvascular anastomosis of the traumatized veins.

This study was carried out to investigate the fine structural changes of rat hepatocytes by repeated treatment of cyclosporin A that has been widely used for immunosuppressive drug in organ transplantation. Sprague-Dawley rats were kept in experimental circumstances for 2 weeks and 50mg/kg B.W of cyclosporin A was injected once a day subcutaneously for 7 days and sacrificed at 1 hour, 1 day, 3 days, 7 days, 14 days, 28 days after the last injection. Fine structural changes were observed by transmission electron microscope (JEM 1200EX II) and the results obtained were as follows. 1. Accumulation of lipid droplets in hepatocytes was prominently increased in 1 hour and 1 day lapse groups, and this finding was slightly reduced in 3 days lapse group and remarkably reduced from 7 days lapse group enough to be recovered completely in 14 days lapse group. 2. Dilatation of rough endoplasmic reticule cisternae, detachment of membrane bound ribosomes, proliferation of smooth endoplasmic reticula were observed in 1 hour and 1 day lapse groups, and these findings were mild in 3 days lapse group and abruptly reduced from 7 days lapse group enough to be recovered completely in 28 days lapse group. 3. Small myelin figures were observed in 3 days lapse group after CsA-treatment. 4. Swelling of mitochondria and destruction of their cristae were observed in 1 hour and 1 day lapse groups, and these findings were recovered from 3 days lapse group. 5. Dilatation of bile canaliculi and remarkable loss of microvilli in the pericanalicular wall were observed in 1 hour lapse group and the most severe change was shown in 1 day lapse group and lasted to 3 days lapse group, and these findings were reduced gradually from 7 days lapse group enough to recovered completely in 28 days lapse group.

To evaluate the possible therapeutic effects of growth hormone and vitamin C on multiorgan failure, a rat model was developed for LPS-induced sepsis. Using this model, the effects of growth hormone and vitamin C on tissue damages, catalase and i-NOS activities, and MDA levels were examined in the lung and liver. The level of TNF- in plasm was also examined. Male, Sprague-Dawley rats were injected with LPS intraperitoneally then divided into 3 groups : positive controls injected with LPS only, the ones injected with growth hormone or vitamin C immediately after the LPS injections. The lung and the liver were then isolated, blood samples were collected at 24 or 48 hours after the LPS injection, then examined for histopathological and biochemical changes. The results obtained were as follows. 1. LPS induced sinusoid vasodilation and mild destruction of lobular structure in the liver. In the lung, alveolar structure appeared to be thickened and interstitial edema was observed. The levels of MDA in the liver and the lung was increased by LPS, while the activity of catalase was decreased. The activity of i-NOS of those tissues was also increased, which was more pronounced at 24 hr. The level of TNF- in plasm was increased by LPS 2. In the lung, vitamin C suppressed lymphocyte and neutrophil infiltration, alveolar wall thickening and interstitial edema. In the liver, vitamin C protected against the destruction of the lobular structure. The activity of catalase reduced by LPS was reversed partly by vitamin C. The activity of i-NOS enhanced by LPS was also reversed by vitamin C. The level of TNF- in plasm reduced in some animals by vitamin C, which however was not significant statistically(p<0.05). 3. Growth hormone showed similar protective effects against inflammation and damages in the liver and lung tissues. Growth hormone reversed partly the LPS effects on the level of MDA, the activity of catalase and i-NOS induction in the liver and the lung. Growth hormone reduced plasma level of TNF-${\alpha}$ substantially, which contrasted from vitamin C. Besides this, overall protective effects of growth hormone against LPS-induced experimental sepsis were similar to those of vitamin C. From this results, the mechanism of growth hormone on suppression of LPS-induced tissue damage might be associated with production of antioxidative enzyme and suppression of plasma TNF- level.

Artemisinin, a new antimalarial to treat patients infected with strains of Plasmodium jalciparum, derived from the plant Artemisia annua Linn, has immunopharmacologic actions such as enhence the PHA -induced lymphocyte transformation rate, increased the weight of spleen but reduced the weight of thymus, reduced phagocytic function of peritoneal macrophage, remarkably reduced the level of serum IgG and hemolysin fonning capacity (sentitized with SRBC), inhibited the activity of Ts cells of donor mice by supraoptimal immunuization(SOI), but enhenced activity of Ts cells of recipient mice by SOI. These results suggested that Ts cells may be the target cells of artemisinin. To the serum complement C3 level of plasmodium berghei-infeted mice, artemisinin (i. m,) could remarkly increase it. The artemisinin also obviously reduced the prostaglandin E(PGE) in the mouse hind paw swelling induced by carrageenin. Numerous studies have demonstrated that pharmacologic doses of PGE attenuate the development of immunocomplex nephritis. Some autologous immune mechanisms may be invoolved In the pathogensis of some types of glomurulonephritis. Glomerular abnormalities can be induced in animals by variety of immunological manipulations. The resulting disorder has many clinical and pathogical similarities to the disease in human. Our purpose was therefore to test the ability of the artemisinin to lessen the severity of rabbit IgG accelerated nephrotoxic serum glomerulonephritis in mice model. Mice which had treated with rabbit IgG and NTS, administrated with saline, showed Significant inceases of urinary protein, cholesterol level, and decrease of serum albumin in NS group. On the contrary, By i.g. adminstration of artemisinin at dose of 12.5, 25 and 50 mg/kg for 14 days after NTS injection, shown that artemisinin inhibited the nephritic changes in some parameters by means of urinary protein(p<0.05, p<0.01) and serum choleterol(p<0.05, p<0.01) and albumin (p<0.05, p<0.01), blood urea nitrogen (p<0.05, p<0.01), serum albumin(p<0.05, p<0.01); Cyclophosphamide(i.p. 10mg/kg for 14d) had almost same effect as the artemisinin had. Morphological studies shown that The picture of kidney from the mouse with NTS-nephritis accerated with rabbit IgG, treated with i.g. saline as the control, the mesangiocapillary were enlarged and proliferated; There were inflammatory cells infiltrating around the glomeruli; The ethelial cell were proliferated in the wall of Bowman's capsule. Histopatholological picture of kidney from the NTS-nephritis accerated with rabbit IgG mouse treated with i.p. 10mg/kg cyclophosphamide as the positive control. No siginicant histopathological evidence were found. Treaded with i.p. 12.5mg/kg artemisinine, the picture shown that mesangiocapillary were lightly proliferated; There were inflammatory cells infiltrating around the glomeruli; Treaded with i.p. 25mg/kg artemisinine, The picture shown that the mesangiocapillary were lightly proliferated; Treaded with i.p. 50mg/kg artemisinine, The picture shown that both the mesangiocapillary proliferated and the inflammatory cells infiltrating around the glomeruli are less than treated with saline, 12.5 and 25 mg/kg artemisinine. On the basis of these studies we conclude that the artemisinin can relieve pathological change caused by NTS-nephritis aacerated with rabbit IgG.
