In this communication, we have discussed the habitat range of two alpine medicinal plants, Aconitum naviculare （Bruehl） Stapf and Neopicrorhiza scrophulariiflora （Pennel） Hong in a trans-Himalayan dry valley of central Nepal, Manang district. They are the most prioritized medicinal plants of the study area in terms of ethnomedicinal uses. A. naviculare occurs on warm and dry south facing slopes between 4090-4650 m asl along with sclerophyllous and thorny alpine scrubs, while N. scrophulariiflora is exclusively found on cool and moist north facing slope between 4000 and 4400 m asl where adequate water is available from snow melt to create a suitable habitat for this wetland dependent species. The soil in rooting zone of the two plants differs significantly in organic carbon （OC）, organic matter （OM）, total nitrogen （N） and carbon to nitrogen （C/N） ratio. Due to cool and moist condition of N. scrophulariiflora habitat, accumulation of soil OC is higher, but soil N content is lower probably due to slow release from litter, higher leaching loss and greater retention in perennial live biomass of the plant. The C/N ratio of soil is more suitable in A. navuculare habitat than that of N scrophulariiflora for N supply. Warm and sunny site with N rich soil can be suitable for cultivation ofA. naviculare, while moist and cool site with organic soil for N. scrophulariiflora. The populations of both the plants are fragmented and small. Due to collection by human and trampling damage by livestock, the population of A. naviculare was found absent in open areas in five of the six sampling sites and it was confined only within the bushes of alpine scrubs. For N. serophulariiflora, high probability of complete receding of small glaeiers may be a new threat in future to its habitat. The information about habitat conditions, together with the information from other areas, ean be useful to identify potential habitats and plan for cultivation or domestication of the two medieinal plants.展开更多

Materials and methods: Data were analyzed on 319 patients (448 feet) from July 1990 to December 2005. Clinical and classification for all patients according to Diméglio. Operated patients were devided into two group: Group1, selective soft tissue release;and Group 2, selective soft tissue release combined with cuboid decancelation. Surgical result were classified according to McKay’s system. Results: There were 103 females (32.3%) and 216 males (67.7%) in this study. There were 192 patients (268 feet) in group 1, 127 patients (180 feet) in group 2. Bilateral involvement was found in 129 patients (40.4%), only the left foot affected in 65 patients (20.4%), and only the right in 125 patients (39.2%). According to the classification of Diméglio Grade II was seen in 32.4%, Grade III in 53,1%, and Grade IV in 14.5%. Postoperatively, in group 1, we got excellent result in 29.1%, good result in 49.2%, fair result in 18.3%, and poor result in 3.4%. In group 2, we attained excellent result in 50.6%, good result in 42.2%, fair result in 6.1% and poor result in 1.1%. The good to excellent result in group 2 was significantly higher in group 1 with p = 0.000042. There was no failure in both groups. Residual adduction of forefoot in frontal plane was seen in 78.0% of group 1, and 10.6% of group 2, which was also statistically significant with p ~ 0. Conclusion: Generally speaking, the procedure of selective soft tissue releases combined with cuboid decancelation showed an outstanding result with good to excellent result of 92.8%. Surgical procedure is simple, safe, and applicable for all patients with clubfeet’s deformyties.展开更多

This is a high velocity injury fracture and can be caused by forcible plantar flexion and inversion of the foot at the time of impact onto the ground. Here we reported such a case in a 35-year-old male patient who was treated by open reduction and fixation with a partially threaded screw and two K-wires for the navicular bone,and two interfragmentary screws with a one third tubular plate for the lateral malleolus. K-wires were removed 6 weeks after surgery followed by partial weight bearing. After 6 months, the patient can walk normally with minimal pain and swelling of the foot.展开更多

No fracture was detected on radiographs and patient was managed conservatively on medications and posterior splint immobilization. We found coincidentally a short fourth metatarsal and an accessory navicular bone in the right foot radiographs. After 3 weeks of immobilization, she underwent mobilization of the right foot, weight bearing and intensive physio- therapy for 6 weeks. After two months of injury she was still complaining of pain on the plantar aspect of right foot which was diagnosed as metatarsalgia and operated on by excision of the neuroma present in the 3rd web space of the right foot. After surgery she was completely relieved of pain and could do activities well related to the right foot.展开更多
