During the last decade emphasis on the medical treatment of herpetickeratitis has generally been laid on the institution of various anti-viralagents and the application of steriods has been the subject of much con-troversy. In this study during 1979, all 100 eyes in 98 patients affected withherpetic keratitis in various stages were successfully treated with sub-conjunctival injections of vitamin C and prednisolone without resortingto anti-viral agents. The duration of illness before starting treatment varied from 4 to 100days: 25 eyes within 30 days, 23 between 30 and 59 days, 39 between 60 and 89 days and 13 over 90 days. Of these diseased eyes,22 were superfi-cial lesions and 78 deep seated ones. Ulcers developed in 43 eyes and 20manifested keratic precipitates. In 46 eyes there was no history of pre-vious attacks while the remainder were relapses associated with vari-ous degrees of scarring and had received all kinds of treatment, includinganti-viral agents and steroids without significant improvement. Therapy was initiated with a subconjunctival injection of a mixtureof 12.5 mg of prednisolone acetate and 100 mg of vitamin C.Subsequentinjections every 3 days consisted mainly of vitamin C, the frequencyand dosage of prednisolone injection depending on the severity of thecondition. The lesion was considered cured if, under the microscope, theedema and infiltration had subsided with return to normal corneal thick-ness, negative staining and clear aqueous associated with subsidenceof subjective symptoms. The results were excellent. All the 100 eyes were cured within anaverage of 12.8 days with extremes of 5 and 50 days. Superficial lesionstook 9 to 11 days, frank ulceration with deep seated infiltration 15days and with iritic involvement 19 days. The curative dosage of vita-min C averaged 480 mg with extremes of 200 and 1,400 mg.For predniso-lone the dosage averaged 40 mg with extremes of 12.5 mg and 100 mg.Short term followup showed that relapses may occur as with any othereffective therapeutic measure. However, a second course of treatmentproved to be equally effective. On the basis of the above therapeutic results and in view of theself-limiting nature of herpes simplex lesions elsewhere in the body andthe constant existence of the virus in the quiescent state, it is postula-ted that the destructive nature of the corneal lesion is due mainly tothe allergic reaction set up by the pathogen, conditioned by immunolo-gical liability of the tissue involved. Treatment of such an optically im-portant structure directed at minimizing reaction, enhancing rapid tissuerepair and perhaps increasing its resistance would not be less reasonableand effective than that directed solely at annihilation of a causativepathogen that stirs up a selflimiting episode. The former rationale wasadopted in this study. However, the mechanism of the combined actionof vitamin C and prednisolone requires further investigation.

The methyl-eugenol is an active principle isolated from the essential oil of Asarum forbesii Maxium. Pharmacological studies showed that methyl-eugenol had marked depressant effect on central nervous system.It was found to potentiate the hypnotic action of pentobarbital and thiopental and the central depressant effect of chlorpromazine. When injected intravenously, methyleugenol showed narcotic effect in rabbits, cats, dogs and monkeys. It caused disappearence of righting-reflex, pain sensation and hearing reflex and slowness of corneal reflex. Average narcotic time with methyl-eugenol varied with different species; rabbits (50mg/kg)13.9, cats (50mg/kg) 9.0; dogs (40mg/kg) 25.0, and monkeys (80mg/kg) 30/0 minutes. It also exhibited marked inhibition of the spontaneous E E G of the cortex and mid-brain RF.Methyl-eugenol exhibited slight depressant action on the cardiovascular system and decrease of blood pressureby 20~30 mmHg in cats and lowering of body temperature in rats.Rapid administration of the drug or overdosage brought about depressant action on respiration (decreased in frequency or even stopp) but it may quickly recover.It may be concluded that methyl-eugenol possesses narcotic action which is similar to commonly used short-acting anaesthetics.

甲基丁香酚(metliyl eugenol)为马辛(Asarum forbesii Maxim)挥发油提得的一个纯品,具有明显的中枢抑制作用:(1)协同中枢抑制药的效应;(2)对多种动物均能产生麻醉作用,且随着剂量变化而麻醉时间长短不同;(3)能抑制免大脑皮层及中脑网状结构的自发脑电活动。此外,给药过快或剂量过大可出现呼吸减慢或停止,但能迅速恢复。持续给药1~2小时或多次给药后进行血象、肝肾功能及各脏器的病理切片等检查,结果除白细胞略有上升外其它均属正常。

Gunshot wounds of the brain stemare usually fatal. Survival followingmissile injury to pons is very rare.As to our knowledge, only threecases have been reported in the Eng-lish literature. An additional case ofthis type of wound in a 17-year-oldmale patient with postoperative sur-vival is here presented. Left abducenspalsy, loss of corneal reflex andaudition, limb ataxia, right centralfacial paralysis, spastic hemiplegiaand hemianesthesia were mainly theclinical signs on neurological exami-nations. After surgical removal of theintracranial retained bullet, the pati-ents improved rapidly in his mentalstate and general conditions. Two anda half years later, a further improve-ment of his neurological deficits wasnoted on follow-up study. In the analysis of these fourreported (three in literature and onejust presented) cases, survival ofpatients from missile injury to thepons may be considered in relation tothe following possible factors: 1) lowervelocity and lesser kinetic energy ofthe bullet. All four patients werepenetrating wounds in type with intra-cranially retained metallic foriegnbodies; 2) Slightly damaged tissuesadjacent to the tract wound. It wasobserved in the early operation oncase I; 3) unilateral injury to the ponswas the common feature of all cases.Clinical diagnosis of this type ofmissile injury can be based on mainly:1) Position of metallic foreign bodies(bullet or fragment) (They were re-vealed in the pons on skull films in thethree previously reported cases); 2)posttraumatic neurological signs. Clin-ical symptoms and signs are correla-tive to the anatomic structures in allfour cases. For the treatment of this type ofmissile injury, first priority shouldbe given to surgical operation. Allcases except case 3 were operated uponeither in the early days of the injuryor in the late post-traumatic stage.In case 1 and case 2, operation wascarried out at 3 hours and 45 minutesrespectively. The operation for case 4was postponed until four months later,owing to the delayed confirmation ofbrain missi1e injury and to the extra-brainstem localization of the bullet. Of these four patients, case 2 wasevacuated following a short period ofobservation. The other three cases ofthe gunshot wounds to the pons withpostoperative survival have been un-dergone long term follow-up studies.
