Dangguijagyagsan(DGJYS) is used in infertile. An attempt was to evaluate the influences of DGJYS on the serum concentrations of FSH, LH and estrogen, the histolgical and optical changes of ovary. The results of the study were as follows : 1. Blood FSH level increased in experimental group as compared with control group on 5th day and 10th day, which showed no efficacy. 2. Blood LH level decreased in experimental group as compared with control group on 5th day and 10th day, which showed no efficacy. 3. Blood E2 level increased in experimental group as compared with control group on 5th day and 10th day, which showed no efficacy. 4. In histolgical observations of ovary, ovulation increased in experimental group as compared control group on 5th day and 10th day, which showed no efficacy. 5. In optically observations of ovary, size of ovary showed no change in exerimental group as compared with control group on 5th day and 10th day. 6. In histological observations of ovary, endometrium showed multiplication. According to these results, the effects of DGJYS are assumed to be usefully utilized for progress of ovulation on uterus and ovary.

Sim, Ju Yong,Kim, Jeongyup,Lee, Won-gil,Cho, Won-Je,Justin Raj, C.,Kim, Byung Chul,Yu, Kook Hyun Springer Science + Business Media 2018 Journal of coatings technology and research Vol.15 No.4

<P>A polybisphenol A epichlorohydrin/antimony-doped tin oxide (PBAE/ATO) polymer composite solution was prepared by utilizing various weight percentages of ATO nanoparticles (similar to 19 nm). The optical properties of the PBAE/ATO composites were analyzed by fabricating thin films on glass substrates. The polymeric film with 3 wt% ATO showed good transparency in the visible and UV regions and strong absorption in the NIR region. Moreover, under light illumination, the PBAE/ATO thin film displayed an similar to 24.4A degrees C rise in temperature relative to the reference thin film. In addition, the outdoor NIR absorption efficiency was studied by spray coating a PBAE/ATO thin film over a vinyl greenhouse, and it was observed that the PBAE/ATO-coated greenhouse prevented snow deposition during the winter by melting the snowflakes through NIR absorption.</P>

The aluminum soundproofing panel used to the traffic noise reduction will judge with the material to improve because the CO2 emission is greater than other soundproofing panel such as plastic soundproofing panel. Also, if the air-passing soundproofing panel which can endure the fast wind velocity will be developed, it judged that it can reached to the target of low CO2 traffic technology development using the reduction of material cost and the lower consumption of steel. The objective of this study is to improve the soundproofing panel and to develop the air-passing soundproofing panel for the replacement of aluminum sound proofing panel which is more emit CO2 than other soundproofing panel. And, we tried to develop the reduction technology of CO2 emission through the development of air-passing soundproofing panel. At first, the flow and noise simulation were conducted for the purpose of the calculation of wind pressure on soundproofing wall and noise exposure level on receiver points according to the open ratio of air-passing soundproofing panel. And the 1<SUP>st</SUP> and 2<SUP>nd</SUP> mockup of air-passing soundproofing panel were made, and the design load test were conducted for these mockup.

Background : This study was planned to evaluate the influence of propranolol and esmolol on cerebral circulation and to estimate clinical implications and usefulness. Methods : This study was designed to measure vital signs, cerebrospinal fluid pressure, cerebral perfu- sion pressure and blood tlow velocity of common carotid artery. This was measured by Doppler Flow meter after intravenous administration of propranolol 12.5, 25, 50 μg/kg (P-12.5, P-25, P-50, respec- tively), and esmolol 0.5, 1.0, 2.0 mg/kg (E-0.5, E-1.0, E-2.0 group, respectively) at 1 or 2 minute intervals for 14 minutes. Results : In the propranolol group (P-12.5, P-25 and P-50), the systolic blood pressure (SBP) significantly decreased since postinjection 1 minute and this decreased pressure continued throughout the entire experiment. But in esmolol group (E-0.5, E-1.0 and E-2.0), the SBP decreased significantly and rapidly recovered within 4 minutes. Heart rate significantly decreased in the propranolol group and continued throughout he experiment, but in the esmolol group the heart rate decreased and rapidly recovered within 10 minutes. The duration of the decreased heart rate in the esmolol group was shortened by decreasing the dosage. The blood flow velocity of the common carotid artery significantly decreased at 1 to 14 minutes after the injection of propranolol, but in group E-1.0, it was significantly decreased at 1 to 2 minutes, and in group E-2.0 at 1 to 3 minutes. Conclusions: The esmolol group showed less changes of SBP, heart rate and comman carotid artery flow, and shorter duration of effect than the propranolol group. Mean blood pressute, cerebrospinal fluid pressure and cerebral perfusion pressure had no significant differences between propranolol and esmolol groups. (Korean J Anesthesiol 2000; 38: 518~527)

Two case of cerebral infestation with Paragonimus westermani complicating obstructive hydrocephalus are presented. The diagnosis was aided by brain CT scan and Conray ventriculogam. Both cases showed a strong positive intradermal test with relevant histories of eating crayfishes in roast form. In simple skull X-ray, one stowed characteristic shell-like calcifications over the temporo-occipital region and the otter showed multiple round calcifications over the suboccipital region. Brain CT scan demonstrated much more characteristic calcifications with marked ventricular dilatation. Conray ventriculogram disclosed obstructive hydrocephalus in both cases, one at the level of the cerebral aqueduct and the other at the level of the fourth ventricle outlet. Both patients were subjected to ventriculoatrial shunts and concommitant Bithionol therapy with marked improvement. The case involving the cerebellum and the fourth ventricle outlet was submitted to the posterior fossa exploration to be verified as a rare cerebellar paragonimiasis.

The authors have studied six patients with histologically proven primary malignant lymphoma of the brain which is still a rare primary brain tumor. The clinical, radiological and pathological findings with results of the treatment are presented. All cases showed a good response to radiation therapy. Therefore, the early diagnosis by computerized tomography scan followed by biopsy or excision is considered to be very important for the BEST results in the treatment. Related reports are discussed briefly.
