Effects of different N sources on growth, nutrient uptake and ionic balance of Larlix gmelini seedlings

The effect of different sources and levels of N on dry matter production, nutrient uptake and ionic balance ofLarlix gmelini was studied. The results showed that the growth of the plants fertilized with ammonium was not as good as the control treatment. The growth of the plants fertilized with ammonium nitrate did not differ significantly from that in control or nitrate treatment, but was better than that in the ammonium treatment. Total cation concentrations in shoots varied little with N level in the ammonium and ammonium nitrate treatments, while those in the shoot increased with N level in the nitrate treatment. The treatments had little effect on the anion concentrations in the shoot. In the roots, the concentrations of both cations and anions changed little except for SO4 2? and Ca2+. There existed a higher carboxylate production in the plants fertilized with nitrate. The ratio between the production of carboxylate and the production of organic N Δ(C-A)/ΔNorg was constant with N supply in the plants receiving nitrate, but obviously declined with N supply for ammonium-fed plants. Δ (C-A)/ΔNorg values were intermediate between those of the nitrate and the ammonium-fed plants as for the mixed N source.

Effectiveness of Ionic Correction along with Conventional Physiotherapy in Patients Recovering from Stroke: A Case Study

Background and Aims: Brain damage caused by stroke is associated with sensorimotor and/or cognitive impairment, depending on area of brain affected and the severity of attack. The aims of this study were to show the importance of physiotherapy associated with electrolyte and mineral balance through diet correction in patients recovering from stroke. Methods: This is a follow-up study of two patients with stroke followed at Kinshasa International Hospital Center during period from May 16 to July 1, 2020. The first had received physiotherapy with foods for correction of the existing ionic and mineral deficiency and the second had only received pharmacological management with conservative physiotherapy without making a change in diet. Clinical and electrolyte monitoring was performed at regular intervals in both patients. The variables of interest evaluated in both patients were FIM, MOTOR/SENSORY and Ionic balance. Results: The parameters of FIM, motors and sensory functions were improved during follow-up, however they remained disturbed in the control. Na+, Cl﹣, K+, Ca2+, and ionic Ca+ improved from intake to discharge. The biological parameters deteriorated during follow-up in the control. At Day 1, only K+ which was higher in the control than the case. At discharge, a significant drop in K+ control was noted (4.1 vs 3.4);of Na+ (142 vs 125) and of Cl﹣ (109 vs 85). Conclusion: The results show that ionic balance by diet correction associated with physiotherapy is more effective than conventional physiotherapy associated with pharmacological management.
