Malassezia furfur is an important causal factor for seborrheic dermatitis. Nowadays, the drugs available to treat this fungal infection are few. Several studies have documented the biological activity of essential oils. However, its antifungal properties are not completely understood, especially its anti-Malassezia activity. The aim of this study were to evaluate the effect of the plant essential oils on the growth of M. furfur using disk diffusion method and analyze by Gas chromatography-mass spectrometry (GC-MS) most active essential oils. In first screening, the 17 plant essential oils have possesses inhibitory activity against M. furfur at 2 mg/mL. Among the plant essential oils, oil of Citrus auranifoli was most active against M. furfur and its activity showed dose dependency. This anti-malassezial activity was high than that of itraconazole at 2 mg/mL. Oil of Citrus auranifolia also was phytochemically examined by GC-MS analysis, its main constituents were identified as limonene, ${\gamma}$-terpinene and terpinolene. It can be concluded that essential oils of Citrus auranifolia may have interesting applications to control fungal-derived diseases.

A theroretical study was made on the psychodynamism of somatoform disorder. Somatoform disorder is caused by a defense mechanism of somatization. Somatization is the tendency to react to stimuli(drives, defenses, and conflict between them) physically rather than psychically(Moore, 1990). Ford(1983) said it is a way of life, and Dunbar(1954) said it is the shift of psychic energy toward expression in somatic symptoms. As used by Max Shur(1955), somatization links symptom formation to the regression that may occur in response to acute and chronic conflict. In the neurotic individual psychic conflict often provokes regressive phenomena that may include somatic manifestations characteristic of an earlier developmental phase. Schur calls this resomatization. Pain is the most common example of a somatization reaction to conflict. The pain has an unconscious significance derived from childhood experiences. It is used to win love, to punish misdeeds, as well as a means to amend. Among all pains, chest pain has a special meaning. Generally speaking, 'I have pain in my chest' is about the same as 'I have pain in my mind'. The chest represent the mind, and the mind reminds us about the heart. So we have a high tendency to recognize mental pain as cardiac pain. Kellner(1990) said rage and hostility, especially repressed hostility, are important factors in somatization. In 'Psychoanalytic Observation on Cardiac Pain', psychoanalyst Bacon(1953) presented clinical cases of patients who complained of cardiac pain in a psychoanalytic session that spread from the left side of their chests down their left arms. The pain was from rage and fear which came after their desire to be loved was frustrated by the analyet. She said desires related to cardiac pain were dependency needs and aggressions. Empatic relationship and therapeutic alliances are indispensable to psychotherapy in somatoform disorder. The beginning of therapy is to discover a precipitating event from the time their symptoms have started and to help the patient understand a relation between the symptom and precipitating event. Its remedial process is to find and interpret a intrapsychic conflict shown through the symptoms of the patient. Three cases of somatoform disorder patients treated based on this therapeutic method were introduced. The firt patient, Mr. H, had been suffering from hysterical aphasia with repressed rage as ie psychodynamic cause. An interpretation related to the precipitating event was given by written communication, and he recovered from his aphasia after 3 days of the session. The second patient was a dentist in a cardiac neurosis with agitation and hypochondriasis, whose psychodynamism was caused by a fear that he might lose his father's love. His symptom was also interpreted in relation to the precipitating event. It showed the patient a child-within afraid of losing his father's love. His condition improved after getting a didactic interpretation which told him, to be master of himself, The third patient was a lady transferred from the deparment of internal medicine. She had a frequent and violent fit of chest pains, whose psychodynamic cause was separation anxiety and a rage due to the frustration of dependency needs. Her symptom vanished dramatically when she wore a holler EKG monitor and did not occur during monitoring. By this experience she found her symptom was a psychogenic one, and a therapeutic alliance was formed. later in reguar psychotherapy sessions, she was told the relaton between symptoms and precipitating events. Through this she understood that her separation anxiety was connected to the symptom and she became less terrifide when it occurred. Now she can travel abroad and take well part in social activities.

Intractable pain from advanced carcinoma of the upper abdomen is difficult to manage. One method used to control pain associated with these malignancies is to block off the splanchnic nerve. In 1919 Kappis described a technique by which the splanchnic nerve of the upper abdomen could be anesthetized, using a percutaneous injection. This method has been used for the relief of upper abdominal pain due to hematoma and cancer of the pancreas, stomach, gall bladder, bile duct, and colon. During the Period from November 1968 to January 1986, this method was used in 208 cases of malignancy at Severance Hospital and clinically evaluated. Patients were retroactively grouped according to the stage of development of technique used. Twelve patients who received the treatment in the period from November 1968 to March 1977 were designate4i as group 1, 26 patients from April 1977 to April 1979 as group 2, and 170 from May 1979 to January 1986 as group 3. The results are as follows: 1) The number of patients receiving splanchnic nerve block has been increasing since 1977. 2) A total of 208 patients, including 133 males and 75 females, ranging in age from 18 to 84 and averaging 51. 3) The causes of pain were stomach cancer 90, pancreatic cancer 69, and miscellaneous cancer 49 cases respectively. 4) There were 57.7% who had surgery. and 3.7% of whom had chemotherapy before the splanchnic nerve block was done. 5) These blocks were carried out with the patient in the prone position as described by Dr. Moore. For group 2 and 3, C-arm image intensifier was used. In group 1, a 22 gauze loom long needle was inserted at the lower border of the 12th rib on each aide about 7\;cm from the midline. The average distance from the midline was $6.60{\pm}0.61\;cm$ on the left side and $6.60{\pm}0.83\;cm$ on the right side in group 2, and $5.46{\pm}0.76\;cm$ on the left side and $5.49{\pm}0.69\;cm$ on the right side in group 3. The average depth to which the needle was inserted was $8.60{\pm}0.52\;cm$ on the left side and $8.74{\pm}0.60\;cm$ on the right side in group 2, and $8.96{\pm}0.63\;cm$ on the left side and $9.18{\pm}0.57\;cm$ on the right side in group 3. 6) The points of the inserted needles were positioned in the upper quarter anteriorly, 51.8% on the left side and 54.4% n the right side of the L1 vertebra by lateral roentgenogram in group 3. The inserted needle points were located in the upper and anterolateral part, of the L1 vertebra 68.5% on the left side and 60.6won the right side, on the anteroposterior rentgenogram in group 3. The needle tip was not advanced beyond the anterior margin of the vertebral body. 7) In some case of group 3, contrast media was injected before the block was done. It shows, the spread upward along the anterior mal gin of the vertebral body. 8) The concentration and the average amount of drug used in each group was as follows: In group 1, $39.17{\pm}6.69\;ml$ of 0.5% -l% lidocaine or 0.25% bupivacaine were injected for the test block and one to three days after the test block $40.00{\pm}4.26\;ml$ of 50% alcohol was injected for the semipermanent block. In group 2, $13.75{\pm}4.88\;ml$ of 1% lidocaine were used as the test block and followed by $46.17{\pm}4.37\;ml$ of 50% alcohol was injected as the semipermanent block. In group 3, $15.63{\pm}1.19\;ml$ of 1% lidocaine for test block followed by $15.62{\pm}1.20\;ml$ of pure alcohol and $16.05{\pm}2.58\;ml$ of 50% alcohol for semipermanent block were injected. 9) The result of the test block was satisfactory in all cases. However the semipermanent block was 83.3 percent of the patients in group 1 who received relief from pain for at least 2 weeks after the block, 73.1% in group 2, and 91.8% in group 3. In these unsuccessful cases, 2 cases in group 1 were controlled by narcotics but 7 cases in group 2 and 14 cases in group 3 received the same splanchnic nerve block 1 or 2 times again within 2 weeks. But, in some cases it was 3 to i months before the 2nd block and in 1 cases even 7 years. 10) The most common complications of splanchnic nerve block were hypotensino(25.5%) occasional flushing of the face, nausea, vomiting, and chest discomfort. 11) For the patients in group 3, the supplemental block most commonly used was a continuous epidural block; it was used as a diagnostic block and to afford relief from pain before the splanchnic nerve block was done. 12) The interval between the receiving of the alcohol block and discharge was from 5 to 8 days in 61 cases(31.1%) and from 1 to 2 days in 48 cases(24.5%). From the above results, it can be concluded that the splanchnic nerve block done in the prone position with pure and 50% alcohol immediately after an effective test block with 1% lidocaine under C-arm fluoroscopic control is satisfactory and reliable. How to minimize the repeat block is still a problem to be solved.
