혼합배양 환경에서 강산성의 초기 운전 조건이 연속식 젖산발효에 미치는 영향

기존의 젖산발효 공정은 순수배양을 통한 회분식 발효를 주로 이용하고 있다. 하지만 멸균과정의 필요와 생산성이 낮은 한계을 가지고 있는 등, 문제점들을 가지고 있어 혼합배양을 통한 연속식 발효가 대안이 될 수 있다. 혼합배양 환경에서는 젖산의 순도와 생산 효율을 높이기 위하여, 젖산균이 우세한 환경을 조성하는 것이 중요하다. 본 연구에서는 젖산균이 강산성 조건에서 뛰어난 저항력이 있다는 기존 연구결과를 바탕으로, 혼합배양 환경에서의 강산성 조건의 초기 운전 조건(pH 3.0)이 연속식 젖산발효에 미치는 영향에 대하여 실험하였다. 초기 운전 조건을 pH 3.0으로 고정시킨 반응기에서 초기 운전 조건을 젖산발효의 최적 pH 조건(pH 5.5)으로 유지한 반응기보다 높은 최대 젖산 농도(6.12 g COD/L), 젖산생성속도(0.51 g COD/L/hr), 수율(0.65 g COD/g COD<sub>removed</sub>), 그리고 함량(94.8% LA/tSOA)을 보였다. 미생물군집구조 분석 결과, 세균군집구조의 변화는 HRT가 짧아질수록 초기 pH조건보다 HRT에 의한 선택압력에 더 큰 영향을 받는 것으로 나타났다. 사사: 본 연구는 환경부의 폐자원에너지화 전문인력 양성사업으로 지원되었습니다.
帶狀疱疹의 臨床的 觀察 및 Triamcinolone 病變的 注射 效果

Herpes zoster is an acute infection of varicellar-zoster (V-Z)virus characterized by groups of vesicles and papules on the erythematous base along the corresponding dermatome of the involved segment in the cranial or spinal sensory ganglia. The treatment of herpes zoster aims at the symptomatic control of neuragia. One hundred and ninety five cases of herpes zoster were clinically observed at the Department of Dermatology of Chosun University Hospital from April 15, 1971 through September 30, 1980. The therapeutic effect of intralesional injection of triamcmolone on herpetic neuralgia was compared with those of systemic corticosteroid and the symptomatic analgesics. The results obtained were as follows : 1) The incidence of herper zoster versus the total number of outpatients wad between 0.50% and 1.89% (on an average, 1.30%) and there was no sexual difference of its incidence. 2) There were no marked monthly or seasonal differences in the incidence of herpes zoster. 3) The herpes zoster was frequently seen in the age of 20 to 29 years old. Considering the age distribution of population in Kwang-ju city. however. its incidence seems to increase with age. 4) Fifteen cases(9.6%.) of the herpEs zoster were seen to be combIned with chronic diseases such as pulmonary tuberculosis, diabetes mellitus and hypsrtension. 5) Herpes zoster was located in the thoracic (46.6%,), trigeminal, cervical, lumbar, sacral and facial nerve dermatomes in that order of frequency. 6) Postherpetic neuralgia was the most common complication with its incidence increasing with age. 7) Thirty nine cases with herpes zoster had intralesional injection with triamcinolone with the following results. Eleven (28.2%) had similar reaction as those treated with systemic corticosteroid and symptomatic analgesics whereas 28 (71.8%) had a more_effective response.

One case of metastatic skin tumor from carcinoma of the ovary was reported with literature re-view. A 20-year-old woman had an episode of total hysterectomy and bilateral salpigo-ophorectomy under the diagnoisis of mucinous cystadenocarcinoma about one year ago. About 2 months ago, a nodule developed on the site of operation wound of the abdomen. Thereafter, multiple nodules developed succeedingly on the abdomen, back and scalp. The nodules were considered to be originated from carcinoma of the ovary in the view of histopathological, immunohistochemical and electron-microscopic finding.

Objectives: The purpose of this study was to examine the effect of combined Korean medical treatment on chronic headache with digestive symptoms. Methods: We collected data from October to December 2020 and evaluated the efficacy of combined Korean medical treatment using the Korean Headache Impact Test-g (KHIT-6), European Quality of Life Five Dimensions (EQ5D) Scale, and Numerical Rating Scale (NRS) at admission, after two weeks of hospitalization, and on discharge. Results: At the end of treatment, the patient had increased EQ5D and reduced KHIT-6 and NRS scores. Conclusions: After the combined Korean medical treatment, the patient showed improvement, suggesting the efficacy of treatment.
