Chapter 11, Problem 5CTQ

(a)

Summary Introduction

To provide:

A reason for whether or not heat is a selective microbial control agent.

Introduction:

Disinfection is a process of removal or cleaning of microorganisms from the surface. It is done by using disinfectants. The disinfectants destroy, inactivate or kill microorganisms. It is a type of chemical agent.

(b)

Summary Introduction

To explain:

The concept of TDT and TDP and also discuss one example of these measurements that can be modified to produce food for human consumption.

Introduction:

Bacteria are defined as small, microscopic, prokaryotic and unicellular organisms that are not seen by naked eyes. They are found everywhere in nature and hence they are called ubiquitous.

Summary Introduction

To determine:

The minimum TDTs for vegetative cells and endospores.

Introduction:

The term TDT, which stands for Thermal death time, is defined as the minimal length of time required to kill bacteria in a liquid culture at a given temperature. It is a type of sterilization technique.

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…
The current nutrition labelling regulation in Hong Kong requires food manufacturer to list E+7 information on the package of pre-packaged food products. Do you think that more nutrients, such as calcium and cholesterol, shall be included?
