Epidemiological studies are important in both the prevention and treatment of mycobacterial infections. This study was initiated to establish the pulsed-field gel electrophoresis (PFGE) method, which are not yet extensively studied. The most apprpriate restriction endonucleases included Dral, AsnI, and XbaI. The optimal PFGE condition was different according to the enzymes used. Two stage PFGE was performed, in case of DraI first stage was performed with 10 seconds of initial pulse and 15 seconds of findA pulse, while the second stage was performed with 60 seconds of initial pulse and 70 seconds of final pu',se. The electrophoresis time for DraI-PFGE was 14 hours for each stage. Electrophoresis was performed for 22 hours, in case of XbaI, with 3 seconds of initial pulse and 12 seconds of final pulse. Electrophoresis was performed for 22 hours, in case of AsnI, with 5 seconds of initial pulse and 25 seconds of final pulse. In all cases the voltage of the electrophoresis was maintained constantly at 200 voltage. Standard mycobacterial strains, which included Mycobacterium bovis BCG, M. tuberculosis, and M. fortuitum, could not be differentiated by PFGE analysis. PFGE analysis was performed to differentiate 9 clinically isolated M. fortuitum strains using AsnI. All M. fortuitum strains showed different genotypes except 2 strains. Cluster analysis divided M. fortuitum strains into 2 large groups. PFGE analysis was performed to further differentiate M. fortuitum isolates using XbaI. The undifferentiated 2 M. fortuitum strains showed different PFGE patterns with Xba I. Cluster analysis of the XbaI-PFGE patterns showed more complex grouping than AsnI-PFGE patterns, which showed that XbaI-PFGE analysis was better than AsnI-PFGE in M. fortuitum genotyping. The top dissimilarity values of AsnI-PFGE and XbaI-PFGE were 0.74 and 0.75, respectively. This value was higher than that of arbitrarily primed polymerase chain reaction (AP-PCR) analysis and lower than that of restriction fragment length polymorphism (RFLP) analysis. This suggested that PFGE can be used as a supportive or alternative genotyping method to RFLP analysis.

2.The pathogenic mechanisms of motor weakness following aneurysmal subarachnoid hemorrhage: A review
Neurology Asia 2017;22(3):185-191
Motor weakness is one of the neurological complication that can occur after aneurysmal subarachnoid
hemorrhage (SAH); incidence of motor weakness of 14~29% has been reported. Detailed information
on the pathogenic mechanism of motor weakness is essential for brain rehabilitation because it enables
estimation of the severity of injury, establishment of scientific rehabilitative strategies, and prediction
of motor outcomes by clinicians. However, the exact pathogenic mechanisms of motor weakness
following aneurysmal SAH have not been clearly elucidated. In this article, 14 previous studies on
pathogenic mechanisms in patients with aneurysmal SAH were reviewed according to the location of
the lesion (cerebral cortex, brainstem, spinal cord, and peripheral nerve). The following pathogenic
mechanisms have been suggested: vasospasm, cerebral ischemia, hydrocephalus, compression of
cerebral cortex, neural injury, spinal cord infarction, and radiculo-neuropathy. Considering the high
incidence of aneurysmal SAH and motor weakness following aneurysmal SAH, we believe that the
pathogenic mechanisms of motor weakness have been relatively understudied. More effort should be
taken to investigate this important topic.

The author measured the value of serum triglyceride, total cholesterol and phospholipid in normal Korean adults and patients with complicated hypertension. Sera obtained from 295 cases of normal Korean male and female, and also 109 cases of patients with hypertension were analysed for triglyceride, cholesterol and phospholipid. The patterns of serum lipoprotein fraction in 171 normal Korean and 109 patients with complicated hypertension including cerebrovascular diseases and ischemic heart disease were studied by agarose gelelectrophoresis. The results are summarized as follows; 1. The mean value of serum triglyceride, cholesterol and phospholipid in normal Korean were 85.4+/-20.5mg%, 187.9+/-16.7mg%, and 193.4+/-34.6mg% respectively. 2. Sex and age difference showed no statistical significance in the mean values of serum triglyceride, cholesterol and phospholipid in hypertensive patients. 3. The mean values of serum triglyceride in the patients with complicated hypertension such as cerebral thrombosis gave higher value than in the patients with other cerebral complications. 4. The mean value of alpha-lipoprotein, pre-beta-lipoprotein and beta-lipoprotein in normal Korean were 29.6+/-5.0% (142.6+/-30.1mg%), 13.0+/-4.3% (62.7+/-24.8mg%), and 57.4+/-30.1% (276.1+/-56.6mg%) respectively. 5. The alpha-lipoprotein fraction in normal Korean demonstrated the tendency of decreasing as age is progressing in both sex, but pre-beta and beta-lipoprotein fraction gave a tendency of increasing by progressing age in both sex, but was not confirmatory in nature. 6. The alpha-lipoprotein fraction in patients with hypertension gave lower value than in the normal subjects, but the value of pre-beta and beta-poprotein were elevated significantly among patients with complicated hypertension than in normal person. 7. The incidence of hyperlipidemia in normal Korean and patients with hypertension were 31.9% and 66.5% respectively. 8. The relative incidences of hyperlipidemic probable phenotypes in normal Korean were as follows: 7% of normal person had Type II (IIa 3.3%, IIb 3.7%), 3.5% had Type III, and 21.4% had Type IV.

The purpose of this paper is to study the effects of anti-inflammatory agents on the blood-aqueous-berrier in experimentally induced uveitis. 10% solution of sodium fluorescein was injection intravenously in the ear vein of rabbits (0.25 ml/kg) and fluorescein curve was drawn after the method of Amsler and Huber. Experimental uveitis was induced by the injection of 0.2 ml of human serwn into the vitreous body. After uveitis had been induced. three kinds of anti-inflammatory agents-Prednisolone, Benzyron and Methotrexate-were Biven oralIy. In control animals in which no uveitis was induced, no changes in fluorescein curve were demonstrated before and after the administrations of drugs. In animals with uveitis, maked increases of the blood-aqueous barrier were noted. When Benoyron and Prednisolone were given to these animals, normaliration of the fluorescein curves were demonstrated. Methotrexate had no effects on the fluorescein curves in uveitis animals, showing no improvements in the permeability of uveal vessela. This ineffectiveness seemed to be due to the resistance of rabbits to methotrexate.

The epidural injection of corticosteroid reduces the inflammatory process of the neural structure and its neighbor structures. Morphine, also injected epidurally, has been reported to alleviate severe pain with the short-acting property. In attempt to prolong the effectiveness of pain relief, we have studied the effect of the epidural injection of the morphine and steroid frorg May 1987 to Oct. 1987, and compared with the effect of the epidural injection of the steroid and local anesthetics from Jan. 1986 to Oct. 1987. In this study, we obtained following results; 1. The major causative diseases were herniated necleus pulposus in 34 cases(48.5%), spinal stenosis in 16 cases(22.9%) and spondylolisthesis in 9 cases(12.9%). 2. In morphine-injected group, 100% of acute group and 92.3% of chronic group was improved. In non-morphine injected group, there was no significant difference between the acute and chroinc groups. 3. The effect of epidural morphine and steroid was as follows; Complete relief 14 cases (63.6%), marked improvement 5 cases(22.7%), moderate improvement 2 cases(9.2%) and no relief 1 case(4.6%). The overall improvement was resulted in 21 cases(95.4%). 4. The effect of epidural steroid and local anesthetics was as follows; Complete relief 10 cases(20.8%), marked improvement 14 cases(29.2%), moderate improvement 12 cases(25%~ and no relief 12 cases(25%). The overall improvement was resulted in 36 cases(75%). 5. The average duration of pain relief was 2.5 months in morphine injected group and 1.3 months in non-morphine injected group. 6. The side effects associated with opiate, such as generalized pruritus, nausea, vomiting and urinary retention were reported in 16 cases(72.7%), but responded readily to Naloxone injection and subsided within 24 hours. It is considered that epidural injection of morphine and steroid prolong the effect and duration of pain relief for low back pain and sciatica when compared with the epidural injection of steroid and local anesthetics.

A 45-Year-old para 1-0-1-1 had submucosal myoma diagnosed by ultrasonogram and hysteroscopic examination. During 60 minutes hysteroscopic myomectomy, 8,000 ml of sorbitol-mannitol distention medium was used and 6,500 ml collected, resulting in a deficit of 1,500 ml. The patient received Ringer`s lactate 1,000 ml intravenously. Her urine output was 400 ml. Blood loss was 40 ml. After operation, hyponatremia(115 mEq/L) was developed and pulmonary edema was also diagnosed clinically at that time and later confirmed by chest radiograph. The judicious administration of diuretics and normal saline fluid replacement to prevent overcorrection to hypernatremia resulted in return of serum electrolytes to normal level and resolution of the pulmonary edema by postoperative day 1. We have experienced a case of pulmonary edema during hysteroscopic myomectomy with sorbitol-mannitol distention medium, which is presented with a brief review of literatures.
