Subsarcolemmal Mitochondria

We evaluated the effect of endurance training (cycling 3 times per week for 12 weeks) on succinate dehydrogenase (SDH) activity in the subsarcolemmal (SS) and intermyofibrillar (IMF) regions of vastus lateralis muscle fibres in 7 individuals (4 females and 3 males). SDH activity of the SS region increased 9.4% and 12.8% in type I and II fibres, respectively (p < .05). SDH activity of the IMF region increased 4.7% and 6.7% in type I and II fibres, respectively (p < .05). This was less than the increase in the SS region (p < .O5). No significant changes were observed in a control group (4 females and 3 males). These data suggest that mitochondria in the SS and IMF regions of human vastus lateralis muscle fibres are sensitive to endurance training. The greater response in the SS region suggests that the metabolic requirements of SS mitochondria were stressed to a greater extent than IMF mitochondria with endurance training. Key words: subsarcolemmal mitochondria, intermyofibrillar mitochondria

Dimensional Electrophoresis

The effects of endurance training on the expression of myosin were electrophoretically analyzed in the deep portion of vastus lateralis muscle from the rat. A 10-wk running program led to increases ( P < 0.01) in myosin heavy chain (MHC) 2a and 2d with a decrease ( P < 0.01) in MHC2b. Training also evoked a rearrangement of the isomyosin pattern with decreases in fast isomyosin (FM) 1 ( P < 0.01) and FM2 ( P < 0.05) and a rise in intermediate isomyosin ( P < 0.01). These changes were accompanied by a 61% decrease ( P < 0.01) in myosin light chain (MLC) 3F (11.8 ± 2.7 vs. 4.6 ± 4.2%). Two-dimensional electrophoresis made it possible to separate the triplet of isomyosins (FMb) consisting of MHC2b. Training elicited a 26% decrease ( P < 0.05) in the FM1b fraction within FMb, i.e., FM1b/(FM1b + FM2b + FM3b) (24.2 ± 5.5 vs. 18.0 ± 4.3%). These changes resulted in a 10% decrease ( P < 0.05) in the MLC3Ffraction, i.e., MLC3F/(MLC1F + MLC3F), in FMb (44.9 ± 4.5 vs. 40.3 ± 3.2%). These results suggest that endurance training may exert the depressive effect on the contractile velocity of type IIB fibers and that a training-induced decrease in the contractile velocity of whole muscle may be caused by alterations in fast alkali MLC complements within a given fiber type as well as by transitions in MHC-based fiber populations.

Ayurvedic Treatment

Myositis ossificansis characterized by heterotopic ossification (calcification) of muscle of various etiologies. It is most commonly affected in the quadriceps of the thighs. There are many tools available for diagnosis of Myositis ossificans, but lack of satisfactory treatment. So the development of a treatment protocol for Myositis ossificans is the need of today`s era. In Ayurveda, the same can be understood as Urusthamba. The present paper discusses a case of Myositis ossificans of right vastus lateralis muscle and its Ayurvedic treatment.

Palate Repair

A 6-year-old girl presented with a large recalcitrant oronasal fistula after bilateral cleft lip and palate repair and numerous secondary attempts at fistula closure. Incomplete palmar arches precluded a free radial forearm flap. A free vastus lateralis muscle flap was successfully transferred. No fistula recurrence was observed at 18 months. There was no perceived thigh weakness. The surgical scar healed inconspicuously. Free flaps should no longer be considered the last resort for treatment of recalcitrant fistulas after cleft palate repair. A free vastus lateralis muscle flap is an excellent alternative, and possibly a superior option, to other previously described free flaps.
