Summary Introduction

(a)

To determine:

The change in the tidal volume if vagus nerves are cut.

Introduction:

Tidal volume is the amount of air inhaled and exhaled during normal breathing. In an adult male, the tidal volume is 500ml. Tidal volume represents the efficiency of the lungs at rest.

Summary Introduction

(b)

To determine:

The change in the tidal volume if phrenic nerves are cut.

Introduction:

The organ system of the body that helps in the process of respiration is termed as the respiratory system. The respiratory system of humans is present in “air-filled” cavity called the thoracic cavity. The thoracic cavity plays a vital role in the process of inhalation and exhalation. It contains a muscular structure called the diaphragm.

Summary Introduction

(c)

To determine:

The change in the tidal volume if intercostal nerves are cut.

Introduction:

The mechanism of breathing involves contraction and relaxation of intercostal muscles. Breathing is controlled by the size of the diaphragm. The contraction and relaxation of intercostal muscles lead to a change in the size of the diaphragm.

1. In vivo testing provides valuable insight into a drug’s kinetics. Assessing drug kinetics following multiple different routes of administration provides greater insight than just a single route of administration alone. The following data was collected in 250 g rats following bolus iv, oral (po), and intraperitoneal (ip) administration.Using this data and set of graphs, determine: (a) k, C0, V, and AUC* for the bolus iv data (b) k, ka, B1, and AUC* for the po data (c) k, ka, B1, and AUC* for the ip data (d) relative bioavailability for po vs ip, Fpo/Fip (e) absolute po bioavailability, (f)Fpo absolute ip bioavailability, Fip MAKE SURE ANSWERS HAVE UNITS if appropriate. SHOW ALL WORK, including equation used, variables used and each step to your solution.

2. Drug quantification from plasma is commonly performed by using techniques such as HPLC or LC/MS. However, these methods do have limitations, and investigators may choose to use a radiolabeled analog of a drug instead. Radioligands are molecules that contain radioactive isotopes, commonly 3H or 14C. This technique allows investigators to quantify drug concentration from radiation measurements. The following measurements were made in 250 g rats following oral administration of 18.2 µCi of a 14C-labeled drug of interest: Time (min) Plasma Radiation Levels (µCi/L) 0 0.0 2 9.7 4 19.2 7 25.3 9 37.8 12 39.6 14 45.8 17 48.8 20 52.0 25 56.4 30 59.2 35 60.1 40 61.1 45 62.1 50 62.8 60 63.1 70 62.1 80 60.1 90 57.3 100 55.5 110 53.7 120 52.2 150 48.0 180 45.0 240 39.0 Note that a µCi is a measure of the amount of radioactivity and hence is a measure of the amount of drug present. Given that the oral bioavailability of this drug is known to be essentially 100%, estimate the following from this…
