The callus of a "Luling"strain of Plantago asiatica was induced by 2, 4-D. When the induced callus was transferred to 2, 4-D free MS medium,budgensis was observed about 2 weeks afterward only by the addition of 6-BA alone. Rootgensis of the bud was stimulated by NAA and 6-BA added to the MS medium thereafter.Finally, the completed plantlet could be obtained.

Many accessories to the ventilator such as the humidifier and the artificial nose are widely used and applied. In clinical medicine engineering, doctors and medical engineers have to be integrated to perform patient-centered care and to accomplish the functional structure based on the patient's essential physiological indexes. The scientific quality control has to be implemented during the operation, maintenance and sterilization of the equipment, thus iatrogenic infection can be avoided and medical diagnosis and treatment can be enhanced.

After enlarging student's enrollment in college,the great change of education and teaching situation took place.In order to improve the teaching quality in medical college,some problems in experiment teaching and their countermeasures were put forward in this paper,such as the experimental kinds and methods of experiment,the arrangement of experiment classes,the fitting out and the use of equipment as well as the modern education techniques and experiment education,etc.

OBJECTIVETo compare five materials commonly used in dentistry, including three types of metals and two types of ceramics, by using different sequences of three magnetic resonance imaging (MRI) field strengths (0.35, 1.5, and 3.0 T).

METHODSThree types of metals and two types of ceramics that were fabricated into the same size and thickness as an incisor crown were placed in a plastic tank filled with saline. The crowns were scanned using an magnetic resonance (MR) machine at 0.35, 1.5, and 3.0 T field strengths. The TlWI and T2WI images were obtained. The differences of various materials in different artifacts of field MR scans were determined.

RESULTSThe zirconia crown presented no significant artifacts when scanned under the three types of MRI field strengths. The artifacts of casting ceramic were minimal. All dental precious metal alloys, nickel-chromium alloy dental porcelain, and cobalt-chromium ceramic alloy showed varying degrees of artifacts under the three MRI field strengths.

CONCLUSIONZirconia and casting ceramics present almost no or faint artifacts. By contrast, precious metal alloys, nickel-chromium alloy dental porcelain and cobalt-chromium ceramic alloy display MRI artifacts. The artifact area increase with increasing magnetic field.

[Objective]To explore the surgical technique and clinical results of minimally invasive incision dynamic hip screws (DHS) in treatment of intertrochanteric fractures in the elderly.[Method]From August 2001 to January 2006,37 old cases (15 males and 22 females, aged from 72 years to 92 years, mean 81.5 years) with intertrochanteric fractures were treated with closed reduction and DHS using minimally invasive technique in our hospital. The procedure included following and critical steps:1～2 k-wires was inserted into the upper part of the femoral head through great trochanter percutaneously after operation. A guide wire was inserted into the center of the femoral head according to 135? collodiaphyseal angle; then, a small incision (4～5.5 cm) was made and along the guide wire for inserting a screw into the femoral head. The guide wire was removed and the side plate was slipped under the soft tissue into to tightly contact the lateral surface of femur, and followed by the side plate barrel being seated on the screw.[Result]The operation time was 40～75 minutes (average 60 minutes) The mean amount of blood loss in, operation was 55 ml. The mean amount of hemoaleh:in showed no significant difference between postoperation and preoperation. The following-up period averaged 15 months (11～18 months) The clinical hone healing lasted for 10～15 weeks. Two cases had mild coxa vara, there were no incision infection, fixation failure or lower extremity rotatory deformity. The excellent rate of joint function was 94.6% according to DONG's assay standard. [Conclusion]Minimally invasive incision DHS has the advantages of shorter operation time, less blood loss, little trauma, less complications and quick functional recovery and is an effective and safe method for treatment of femoral intertrochanteric fractures in the elderly.

[Objective]To evaluate the clinical characteristics and effect of operative treatment for the ossification of ligamentum flavum thoracic spinal stenosis (OLF-TSS). [Methods]From October 1998 to February 2007,38 patients with OLF-TSS were treated with en bloc hemi-articular process laminectomy. In this group,25 cases were male,and 13 cases were female. The average age was 48 years (range,29～71 years). Totally 81.6% of the lesion was between T10～L1 intervertebral disc space.The average history was 10 months. There were 5.3 percent with protrusion of intervertebral disc of thoracio spine.[Results]Thirty-eight cases were followed-up for 1～8 years,with an average of 3 years and 6 months. Dural injury occurred in 4 cases of 38,3 cases appeared postoperative cerebrospinal fluid leakage. All cases were cured conservatively mainly with bed rest in the prostrate position. According to WANG's evaluation,25 had excellent results,11 had good results,2 had no change and none was poor,The excellent to good rate was 94.7% in this group. There were no patients with the wrong level. No patient neurological functions were deteriorated.[Conclusion]The chinical features of OLF-TSS are very complex. The common symptoms of the disease are progressive onset of numbness,weakness,low back pain,intermittent claudication of the lower extremities,constriction on trunk or lower limbs and sphincter dysfunction. The clinical presentation and neurological examination associated with X-ray film,MRI and CT were the important means of the diagnosis of the disease. Removal of the posterior wall of the thoracic spinal canal via the technique of en bloc hemi-articular process laminectomy is safe and effective to treat OLF-TSS. The strategy for diminishing fault and complications is to discriminate pathogenic segment (locating-diagnosis) and follow the principles of surgical procedure.

Eight cases of human rabies encephalomyelitis confirmed by autopsy were reported. They all had a history of rabid dog bite and typical clinical manifestations of rabies. The mean clinical course ran about 4 days. The most frequent pathological findings were the appearence of intracytoplasmic Negri bodies in neuron and paren-chymal inflammation of the brain and spinal cord. The inflammatory response was more prominent in the brainstem, hippocampus and spinal cord, consisting of peri-vascular cuffs of lymphocytes and monocytes, foci of softening microglial response and neuronophagia. Negri bodies were found in all of the sections taken from the brain, especially frequently found in the purkinjs cells of the cerebsll um and the pyramidal cells of the hippocampi in all the eight cases.The pathodiagnostic principles of this disease, and its differentiation from type B encephalitis and polimyelitis were briefly discussed. The relation between the site of the dog bite and the distribution of the lesions and the duration of the incubation period were also discussed.

Observations on the developement of pathological changes of rat brain, together with dynamic detection of CN- concentrations in blood and brain tissue and quantitive analysis of brain cytochrome oxidase activity, are carried out within 24 h after acute cyanide intoxication (4.5mg/kg i.p.) . The results indicate that in the cyanide poisoning with the dose under lethality (80%LD) , the pathological changes in rat brain appear, especially in cytochrome oxidase poorly- contained areas, including! 1 ) degeneration and necrosis of neurons and gliocytes; 2) degeneration, swelling and lysis of different cell projection components; 3) the myelinoclasis of myelinated nerve fibers. Those changes undergo a dynamic course divided into three phases: 1 ) the phase of metabolic disturbance; 2) of response to injury; and 3) of restoration. The authors consider that the acute poisoning displayed by the animal after NACN injection is directly caused by the intense inhibation of brain cytochrome oxidase; the secondary lesions of brain structure may be responsible for the manifestations such as trembling, unstable, and ataxia etc.occur later. The mechanisms of the brain pathological changes after cyanide intoxication are also disscussed.

Thirty percent TBSA full thickness burns due to napalm was inflicted to the rats and the pathological changes of the thyroid were studied under optical and electron microscopy and with peroxidase histochemistry for 15 days. The alterations of serum T3 and T4 levels accompaniying the pathological changes were also observed dynamically.It was found that the pathological changes of the thyroid could be distinguished into three phases as follows.1. The phase of injury inhibition. This phase existed from the 2nd to the 24th hour postburn and was characterized by marked damage on the follicular epithelium.2. The phase of structural and functional recovery. This phase entended from the 3rd to the 6th day postburn. In this phase, the damages on the thyroid became abated and its damaged structure showed a tendency to recover.3. The phase of active function. It extended from the 10th to the 15th day postburn. The organelles to synthesize and release thyroid hormone were fonud well developed.The alteration of T4 run parallelly to the pathological changes of the thyroid in all the stages, while T3 level was continously inhibited because of the lower serum concentration of T4, the metabolic disturbance of T4 deiodination, and the inhibition of thyroid secretion in the early postburn stage and the metabolic disturbance of T4 deiodination in the middle and late postburn stages. In the early postburn stage, the inhibition of thyroid peroxidase was an important factor of functional inhibition of the thyroid.
