A 81-year-old man was referred for respiratory failure by emergency medical technicians. He admitted at intensive care unit for ventilator treatment. Several hours before admission, he took sildenafil 100 mg for erectile dysfunction without prescription. The episodes of hemoptysis occurred several hours later. Computed tomography revealed multifocal diffuse ground-glass attenuation in both lungs. And the more we performed bronchoalveolar lavage, the more the color of it was turned into red. We treated him with empirical antibiotics and tranexamic acid, and hemoptysis was stopped in one day after admission. But in the 5th admission day, he died from sepsis combined with pneumonia caused by Acinetobacter baumannii abruptly.

BACKGROUND AND PURPOSE: Valproic acid (2-propylpentanoic acid) which enhances GABA synthesis and blocks it's degradation has been useful treatment of migraine and may activate GABA receptors to modulate trigeminal nociceptive neurons innervating the meninges. But the mechanism and action of sodium valproate in headache is not clear. To investigate the mechanism of valproic acid action in headache model, we compared the change of dural plasma protein extravasation in both substance-P neurogenic inflammation rats with valproic acid pretreatment and without valproic acid pretreatment. METHOD: Sprague-Dawely rats were pretreated with valproate 30 minutes prior to substance-P administration in order to test the effects of sodium valproate on dural plasma protein extravasation by detecting the amount of extravasated Evans blue in the dura matter. To examine the abilities of either bicuculine (GABAA antagonist) and phaclofen (GABAB antagonist) to reverse the effect of valproate, they were administered 5 min before valproate administration. After then we also test the effect of muscimol (GABAA agonist) and bicuculine (GABAA antagonist) in substance-P induced neurogenic inflammation rats. RESULTS: Intraperitoneal injection of sodium valproate and muscimol reduced dural plasma protein extravasation after intravenous substance-P administration. The GABAA antagonist bicuculine completely reversed the effect of valproate and muscimol on plasma extravasation following substance-P administration, whereas the GABAB receptor antagonist, phaclofen, did not. CONCLUSION: We concluded that the attenuation of dural plasma protein extravasation by valproate and muscimol is mediated by via GABAA receptors within the meninges. Agonists and modulators at the GABAA receptor may become useful for the development of selective therapeutic agents for migraine headache.

Pulmonary vascular hypertension is characterized by migration and proliferation of smooth muscle cells accompanying abnormal synthesis and accumulation of extracellular proteins in vascular wall. The aim of this study is to define the role of endogneous TGF-betas and PDGF in the process of remodeling vessels through determining the temporal and spatial distribution of these growth factors in hypertensive pulmonary vessels in monocrotaline-induced pulmonary hypertension in rat. Sprague-Dawley rats were sacrificed 12 hours, 1, 2, 4, 7, 10, 14, 21, 28, and 56 days after treatment. The morphometric analysis of medial thickening and immunohistochemical study using antibodies to TGF-beta1, TGF-beta2, TGF-beta3, and PDGF were performed. Immunoreactivities for TGF-beta1 and TGF-beta3 were increased from the 14th day in the medial smooth muscle cells and PDGF showed increased expression from the 21st day in the medial smooth muscle cells. No difference in TGF-beta2 immunoreactivity was found between control and experimental groups. The expression of TGF-beta1, TGF-beta3 and PDGF increased in medial layers with the progressive thickening of pulmonary arteries which was considered to have close relation to medial hypertrophy of pulmonary arterioles. In the case of PDGF, however, the morphologic change occurred before increase in immunoreactivity was observed in the medial layer of pulmonary arterioles. Moreover, the function of isoforms of TGF-beta has yet to be completely elucidated; the different affinity to receptors and the degree of expression of these receptors that are supposed to affect the function of growth factors. Thus, further studies are needed.

Paraganglioma is a benign tumor arising in the paraganglion system scattered throughout the body, but its cytopathologic findings arenot well known. We experienced a case of paraganglioma of carotid body diagnosed by fine needle aspiration. The patient was a 30 year-old female who suffered from the left neck mass for 3 years. The mass was 3x3crn in size without pulsation or bruit. Cytologically, the smear revealed aggregated and singly scattered tumor cells having abundant pale cytoplasm and indistinct cell borders. Their nuclei were round to oval, but enlarged nuclei were occasionally observed. The nuclear membrane was smooth with fine clumping of chromatin. Differentiation from metastatic follicular carcinoma of the thyroid gland was difficult.

Alcoholic celiac plexus blocks have been used to relieve intractable upper abdominal cancer pain. Various techniques have been proposed including the use of the X-ray and CT scanner to improve results and to avoid complications. We used the CT scanner and the X-ray fluroscope for 36 cases of alcoholic celiac plexus blocks to determine the depth and position of the needle without previous diagnostic blocks. Good to excellent pain relief occurred in more than 72% of the patients and the advantages of the use of the CT scanner showed that 1) placement of the needle tip is easily established according to the surrounding anatomical structures. 2) the operator can introduce the needle without anxiety. 3) the time required for block are saved.

This study was attempted to cumpare the effects on blood glucoge of 5% Dextrose in Water (D5W) and Hartmann's solution infused during halothane anesthesia.20 female patients in the state of A.S.A. classification 1 were chosen and divided into 2 groups, i.e. first group D5W. the second group Hartmann's solution. Blood samples were collected on the operating table prior to starting I.V. infusion, after 1/2 hour, 1 hour and 11/2hour from the time 1.V. infusion started. Intravenous fluid was administered at 10 ml/kg/hr. Changes of blood glucose levels were as follows. In the group of D5W, the values of bleed glucose were 83.4+/-13.5 mg% at N.P.O., 198.4+/-33.6 mg% at 1/2 hour, 245.5+/-55.6mg% at 1 hour, and 259.5+/-40.1 mg% at 11/2 hours. In the group of Hartmann's solution, the values of blood glucose were 64.9+/-9,5 mg% at N. P.O., 93.3+/-21.9mg% at 1/2 hour. 99.0+/-15.6mg% at 1 hour, and 105.6+/-24.2mg% at 1 1/2hours.
