2.THE CUTANEOUS BRANCH OF THE SUPRASCAPULAR NERVE IN CHINESE
Acta Anatomica Sinica 1955;0(03):-
A cutaneous branch of the suprascapular nerve was observed in 9 from 180 Chinese adult arms (5.0?1.62%), it has been found bilaterally in 3, and unilaterally in other 3 male cadavers.The cutaneous branch arose from the stem of an essentially normal suprascapular nerve under the superior transverse scapular ligament. After passing between the coraco-clavicular and coraco-acromial ligaments the cutaneous branch pierced obliquely the deltoid muscle and supplied the proximal third of the antero-lateral aspect of the arm. The distribution territory of the cutaneous branch coincided with the anterior half of the deltoid muscle.

Objective To determine the effect of enflurance on nitric oxide synthase (NOS) activity and nitric oxide (NO) content in different brain regions at different anesthesia stages.Methods Forty female SD rats weighing 250-350 g were randomly divided into five groups of 8 animals each, group 1: control; group 2: induction of anesthesia; group 3: maintenance of anesthesia; group 4: recovery from anesthesia and group 5: complete recovery. Animals were placed in a special glass anesthesia box. The concentration of enflurane in the box was measured by anesthesia gas monitor (Normac). The induction of anesthesia started from staggering of the animal to loss of righting reflex, maintenance of anesthesia from 1 min after loss of righting reflex, recovery of anesthesia from recovery of righting reflex to staggering after enflurance anesthesia was discontinued and glass box was opend and complete recovery from 1h after recovery of righting reflex. The animals were decapitated at different stages of anesthesia. Cerebral cortex, hippocampus and brain stem were immediately removed on ice and frozen in liquid nitrogen. Their NOS activity and NO content were measured by spectroscopic analysis. Results The average duration from the beginning of 2.2% enflurane inhalation to loss of righting reflex was (169?30) s. The average duration of anesthesia induction was (138?36)s. The maintenance of anesthesia lasted (229?30) s and the recovery period averaged (266?41) s. The NOS activity and NO content in different brain regions began to decrease during induction of anesthesia and reached their lowest level during maintenance of anesthesia, began to increase during recovery from anesthesia and returned to preanesthetic level during complete recovery. Conclusion Enflurane significantly inhibits the NOS activity and NO content in the brain. The inhibits is closely related to the depth of anesthesia. NO is a message transmitter in central nervous system and may be involved in the mechanism of enflurane anesthesia.

Objective To investigate the effect of thiopental sodium (TPS) on spontaneous and KCl-evoked glutamate release from prefrontal cortical synaptosomes in rats and the effect of bicuculline on this effect ofTPS.Methods SD rats of both sexes (200-250 g) were decapitated and brains were removed. The prefrontalcortex was dissected and added to ice-cold sucrose solution and homogenized. The homogenate was centrifuged at1000 g at 0℃-4℃ for 5 min. The supernatant was again centrifuged at 12 000 g for 20 min. The sediment wascrude synaptosomes, which was added to artificial cerebro-spinal fluid (ACSF). The crude synaptosomes weredivided into 5 groups (n = 8): control group and 4 TPS groups. In control group no TPS was added while in TPSgroups different concentrations of TPS was added and the final concentration of TPS was 10, 30, 100, 300?mol?L~(-1) respectively. The synaptosomes were then placed with or without KCl in water bath at 37℃ for 15 min. Thespontaneous or KCl-evoked glutamate release was measured using high-performance liquid chromatograph (HPLC).In another set of experiment bicuculline 0. 1 mmol?L~(-1) was added to ACSF in each group before 15 min water bathto see if it could antogonize the effect of TPS on glutamate release. Results TPS 30, 100 and 300 ?mol?L~(-1)could significantly inhibit the spontaneous or KCl-evoked glutamate release compared with control group (P0.05). Bicuculline 0. 1 mmol?L~(-1) had no effect on the glutamate release in control group but could antagonize the inhibitory effect of TPS on glutamate release. Afteraddition of bicucculline the glutamate released in control group was not significantly different from that in the TPSgroups.Conclusion TPS sodium can inhibit the spontaneous or KCl-evoked glutamate release from prefrontalcortical synaptosomes in a concentration-dependent manner. The inhibitory effect is mediated by GABA_A receptors.

AIM: To investigate the dynamic changes of ATPases and NOS activities and NO production at different anesthesia phases using thiopental and propofol andifferent anesthetic phases (induction, anesthesia, restoration, and awake), the activities of NOS and ATPase and NO production in cortex and brain stem were meagroup. RESULTS: Ca2+ -ATPase and Na+ ,K+ -ATPase activities in the cortex and brain stem were significantly decreased after administration ofthiopental and propofol,especially at induction, anesthesia, or even restoration phase of thiopental group (P<0.05, P<0.01) and at anesthesia phase of propofol group (P<0.05). NOS activities and NO production decreased from induction to restoration phase with thiopental and propofol anesthesia (P<0.01). The parameters were returned near to the normal at awaken phase. CONCLUSION: Activities of ATPases and NOS and the production of NO may mediate the anesthesia effects of thiopental and propofol in the rat cortex and brain stem.

Objective To investigate the effect of isoflurane pretreatment on hypoxia/reoxygenation (H/R)-induced syndecan-1 shedding from human umbilical vein endothelial cells (HUVECs) . Methods HUVECs were cultured in EMB-2 medium and randomly divided into 3 groups ( n = 32 each) : control group (group C), H/R group and isoflurane pretreatment group (group I). H/R was produced by 4 h exposure of HUVECs to hypoxia followed by 2 h reoxygenation in H/R and I groups. HUVECs were exposed to the mixture of 5% CO2 and 95% O2 for 30 min and then cultured in normal culture atmosphere (21% O2) in group C. In group I, HUVECs were expased to 1.73% isoflurane and incubated for 30 min before H/R. The syndecan-1 expression, concentrations of shed syndecan-1 in the medium, and cell permeability and viability were measured at the end of reoxygenation. Results Compared with group C, the shed syndecan-1 concentration in the medium and cell permeability were significantly increased, while the syndecan-1 expression and cell viability decreased in H/R and Ⅰ groups ( P < 0.01) . Compared with group H/R, the shed syndecan-1 concentration in the medium and cell permeability were significantly decreased, while the syndecan-1 expression and cell viability increased in group Ⅰ (P < 0.01) . Conclusion Isoflurane pretreatment can protect HUVECs against H/R injury through inhibiting the syndecan-1 shedding.
